Download Matkad in Russian. Math built-in functions

Mathcad - software tool, an environment for performing a variety of mathematical and technical calculations on a computer, equipped with an easy-to-learn and easy-to-use environment graphical interface, which provides the user with tools for working with formulas, numbers, graphs and texts. More than a hundred operators and logical functions designed for numerical and symbolic solutions are available in the Mathcad environment mathematical problems of varying complexity.

To automate mathematical, engineering and scientific calculations, a variety of computing tools are used - from programmable microcalculators to ultra-powerful supercomputers. And yet, such calculations remain difficult for many. Moreover, the use of computers for calculations has introduced new difficulties: before starting calculations, the user must master the basics of algorithmization, learn one or more programming languages, as well as numerical calculation methods. The situation changed significantly after the release of specialized software systems for automation of mathematical and engineering calculations.

Such complexes include software packages Mathcad, MatLab, Mathematica, Maple, MuPAD, Derive, etc. Mathcad occupies a special position in this series.

Mathcad is an integrated system for solving mathematical, engineering and scientific problems. It contains a text and formula editor, a calculator, scientific and business graphics tools, as well as a huge database reference information, both mathematical and engineering, designed in the form of a reference book built into Mathcad, a set e-books and ordinary “paper” books, including those in Russian

A text editor is used for entering and editing texts. The texts are comments, and the mathematical expressions included in them are not executed. The text can consist of words, mathematical symbols, expressions and formulas.

The formula processor provides a natural “multi-story” set of formulas in familiar mathematical notation (division, multiplication, Square root, integral, sum, etc.). The latest version of Mathcad fully supports Cyrillic letters in comments, formulas and graphs.

The computer provides calculations using complex mathematical formulas, has big set built-in mathematical functions, allows you to calculate series, sums, products, integrals, derivatives, work with complex numbers, solve linear and nonlinear equations, as well as differential equations and systems, carry out minimization and maximization of functions, perform vector and matrix operations, statistical analysis, etc. You can easily change the bit depth and base of numbers (binary, octal, decimal and hexadecimal), as well as the error of iterative methods. Dimensions are automatically controlled and converted into different systems measurements (SI, GHS, Anglo-American, and custom).

Mathcad has built-in symbolic mathematics tools that allow you to solve problems through computer analytical transformations.

The GPU is used to create graphs and charts. It combines ease of communication with the user with great capabilities of business and scientific graphics. The graphics are focused on solving typical mathematical problems. It is possible to quickly change the type and size of graphs, overlay text labels on them and move them to any place in the document.

Mathcad is universal system, i.e. can be used in any field of science and technology - wherever they are used mathematical methods. Writing commands in the Mathcad system in a language very close to the standard language of mathematical calculations simplifies the formulation and solution of problems.

Mathcad is integrated with all other computer counting systems.

Mathcad makes it easy to solve problems such as:

· entering various mathematical expressions on a computer (for further calculations or creating documents, presentations, Web pages or electronic and regular “paper” books);

· carrying out mathematical calculations (both analytical and using numerical methods);

· preparation of graphs (both two-dimensional and three-dimensional) with calculation results;

· input of initial data and output of results to text files or database files in other formats;

· preparation of work reports in the form of printed documents;

· preparation of Web pages and publication of results on the Internet;

· obtaining various reference information

and many other tasks.

Starting from version 14, Mathcad is integrated with Pro/ENGINEER (as well as SolidWorks). The basis of the Mathcad and Pro/ENGINEER integration is the two-way communication between these applications. Their users can easily link any Mathcad file with a Pro/ENGINEER part and assembly using the Pro/ENGINEER system feature analysis feature

Mathcad creates a convenient computing environment for a wide variety of mathematical calculations and documentation of work results within the framework of approved standards. Mathcad allows you to create corporate and industry certified calculation tools in various fields of science and technology, providing a uniform methodology for all organizations included in the corporation or industry

Mathcad 14

The latest version of Mathcad supports 9 languages, allowing for more powerful and clear calculations.

NEEDHAM (Massachusetts). On February 12, 2007, PTC (Nasdaq: PMTC), a CAD/CAM/CAE/PLM systems development company, announced the release of Mathcad 14.0, the most latest version popular system automation of engineering and technical calculations. Since acquiring Mathsoft in April 2006, PTC has focused its efforts on further expanding the geographic reach of Mathcad technology and significantly increasing its user base. Mathcad 14.0 significantly expands the capabilities of users in solving ever-growing computing problems, improves the connectivity of calculation documents throughout the entire product development process.

In modern conditions of global division of the product development process, scientific and technical calculations become extremely important. With the release of Mathcad 14.0, PTC provides full support for Unicode and will soon offer this product in nine languages. New among them will be languages such as Italian, Spanish, Korean and both Chinese - traditional and simplified. Expanded language support in Mathcad 14.0 will allow geographically dispersed teams to perform and document calculations in their local language and, as a result, increase productivity by increasing speed and accuracy, as well as reducing errors that occur when translating from one language to another.

Mathcad 14.0 also allows you to perform more complex calculations while keeping them clear with new WorkSheet features (a document opened in the Mathcad environment), additional funds operational numerical evaluation and extended character set. This will help users when deriving formulas, displaying computing process and documentary substantiation of calculations. Ultimately, special additional features will allow users to work with more wide range engineering and technical tasks.

The basis of the Mathcad and Pro/ENGINEER integration is the two-way communication between these applications. Their users can easily link any Mathcad file to a Pro/ENGINEER part and assembly using the Pro/ENGINEER analysis feature. Basic quantities calculated in the Mathcad system can be converted into parameters and dimensions of a CAD model for controlling a geometric object. Parameters from the Pro/ENGINEER model can also be entered into Mathcad for subsequent engineering calculations. When parameters change, the mutual integration of the two systems allows you to dynamically update the calculations and drawing of the object. Moreover, now the correctness controlled by the system Mathcad Pro/ENGINEER models can be validated using Pro/ENGINEER calculation modules such as Pro/ENGINEER Mechanica®, Structural And Thermal Simulation, Fatique Advisor Option and Mechanism Dynamics Option.

What's new in Mathcad 14.0?

· New tandem of interface operators (“Two in one”)

· Format of numbers on graphs

Almost any engineering or physical problem involves a large number of mathematical calculations. For a long time this was a routine and took up a huge amount of time, or to be more precise, about 80%. With the invention of the computer, and later of special tasks, such calculations became much easier. Today, RTS MathCad is considered one of the most popular and easiest to use.

History of creation

The first version was released in 1986 and at that time was an indispensable assistant engineers. Even then, in addition to simple and complex algebraic calculations, it was possible to construct 2D graphics. A little later, the program was taught to build 3D graphics. However, development was greatly hampered by the weak computing capabilities of computers.

Alen Razdov, the man who invented and wrote the first version of the program, understood perfectly well what most users needed and by the 5th version he implemented what in the future became one of the main advantages of the editor. This was the opportunity to connect your own functions to the program.

The required function could be written in C, compiled and attached to the program via a DLL mechanism. To make it clearer what’s so cool about this, we can give an example.

Every day at work an engineer faces big amount miscalculations. Surely certain pieces of calculations are repeated from time to time. Yes, the program already made it possible to even copy already written formulas and simply change the input values, but at the same time the calculations still remained visually large. The program made it possible to hide this entire algebraic part by creating a function. In the future, all this will be replaced with just one line. Convenience and comfort.

Speaking of convenience, one cannot fail to mention the wonderful, friendly interface. The functions that are most often used are displayed on a separate panel, which, by the way, can be changed to suit you. The second point is to use the principle “what you see is what you get.” That is, when working in the program, you visually observe everything in the same way as if you wrote everything on paper. This is also an advantage when you need to print a document. In fact, after just 30 minutes of studying, you can start working fully in the editor. In worldwide network, you can also download MathCad torrent at high speed.

There is no particular point in examining the early versions of the program in detail, and therefore we will immediately move on to 2006, when the Mathsoft company, created by Alan Razdov, was bought by PTC Corporation. Together they began to develop the next versions.

Features of MathCad 14

The main thing to note is the change in the core of the program. The previously used Maple subsets were replaced with the algebraic kernel MuPad. This increased the accuracy and quality of calculations, which is undoubtedly a plus, but added problems for users. The fact is that some files created in earlier versions Now they could simply not open in MathCad 14, download the torrent, which is available on the website. And if they did open, there was no confidence that everything was working correctly. Therefore, people who had already worked with the editor for a long time were very reluctant to switch to the new version.

There were many changes in the program, for example, the introduction of full support for all Unicode fonts or spell checking in 15 languages, but these are all minor things. What is really important for the user is the introduction of the tandem operators “… := … = …”. Now you could assign an expression to a variable and immediately get a solution. It would seem that this is not significant at all, but this is another step towards the standard and regular recording calculations and avoidance of program and machine recording.

Three new solution algorithms have also been added differential equations and several new features in the character processor.

It cannot be said that many people wanted to download Matcad 14, but the decisive factor for some was the integration with the Pro/ENGINEER package. This provided enormous opportunities in the complex of engineering and design work. Now it has become much simpler and easier to build a model using calculations or carry out calculations taking into account the geometry of the model. Even those who did not particularly like one or the other program switched to this combination, simply because of the time savings.

MathCad 15

It was possible to download MathCad 15 torrent already in 2010. A number of functions were improved and integration with various databases, such as KnovelMath and Truenumbers, continued. That is, PTC continued to make the program as convenient as possible and expand its capabilities.

The most important thing to note, in contrast to previous version is an extension of the calculation functionality for planning experiments. And of course, we added support for new ones Windows time 7 and Excel 2007. You can download Matkad 15 directly on our website.

MathCad Prime

The next significant stage in the development of the program after the purchase of MathSoft by PTC Corporation and the replacement of the algebraic core was the release of MathCad Prime. You could say it's perfect new program, simply written taking into account previous experience gained from creating “digital versions”. A new version Indeed, it was written completely from scratch, has an updated package of functions, including for planning experiments. Works without problems on Windows 7 and supports MS Excel.

The editor has also become more “alive”. Simple new interface and text notes for calculations very quickly made it a favorite program of higher education educational institutions And small companies. It is difficult to find a modern engineering student who neglects this program. It allows you to easily and quickly make both strength calculations and solve problems based on discrete mathematics. At the same time, if errors occur, and they do occur, then it is enough to correct several variables and not have to recalculate everything again. The program changes everything for you. This approach also greatly facilitates the solution of design problems in which there are several rounds of iteration.

MathCad Prime 3.0

The version was presented to the public on October 16, 2013. The developers themselves highlight the following features and capabilities:

Global definition of variables. This means that you can set the value of a variable anywhere in the worksheet without worrying about the sequence of calculations. If the calculation scheme is not standard and the program does not define it, then you can use the “if” and “then” program functions.
Mathematics and text are one. After all the calculations have been carried out, you will not need to formalize them and bring them to a presentable form in some other program. Good built in text editor, which allows you to add various notes, explanations and entries. At the end, you will receive a document that you are not ashamed to print out and take to the teacher for checking.
Creating templates. When you often use the program and work in one area, it will be quite convenient to create templates that already include a certain set of formulas, text, etc. This frees you from having to do the same work every time, moving on to another task.
Formatting. As mentioned above, the program has a built-in text editor with a sufficient range of capabilities. But you can use it to edit and format formulas.
Function integration. Despite the fact that more than 3 thousand functions are built-in, it is impossible to cover absolutely all disciplines. Therefore, it is possible to program and add your own functions for further convenient use.
Excel integration. Most often, a large amount of data after various measurements or the like is stored in Excel tables. But many are not satisfied with the charting functionality that this software provides. The editor easily recognizes such tables and makes it possible to both export and import them.
Symbolic calculations and formulas. It is not always possible, and sometimes even the desire, to carry out all the calculations numerically. It is possible to calculate everything character by character, enter the initial data and only at the end get the power value.
Graphical tools. Need to build a complex spatial graph? You just need to download Matkad 15 torrent and do it with it easily and quickly.

MathCad Prime 4.0

Can complex engineering calculations be trusted? spreadsheets? Never. That's why engineers choose this application as their calculation tool. In the spring of 2017, PTC released the most anticipated version by users software, which makes it easier to manage and protect your calculations so you can share them securely with others. The main innovations in the program concerned primarily security, performance and ease of use. The new version lets you organize and interact with large, complex documents, offers security and scope locking so you can control the level of access, and you can now embed content created in other apps into documents. So why should you choose a new product:

Secure transfer of design intent and design knowledge.
Clear calculations using standard mathematical representation.
Create professional-quality documents using active mathematical formulas, graphs, text and images.
Adaptation of standard calculations.
Increases productivity with full support for units of calculation throughout the calculation.
Accelerate learning and adoption with instant access to eLearning content.

With the purchase of Mathsoft by PTC, marketing also changed. Not everyone needs it full version programs. Therefore, it was decided to divide it into different packages. Next comes the division into an individual version, a multi-user version and a special educational version, which comes at a very reduced price and does not require certain confirmations and requests from educational institutions.

A special web interface has also been developed for which you do not need to purchase or install the program itself. However, this will not be superfluous, since with a purchased license the web interface gives more high level access.

If you want to download the Russian version of Matkad for free, you can do this on the website in one click.

MathCad Prime 5.0

Performing complex engineering calculations and their visual presentation – different tasks, requiring various specific software. However, PTC developers managed to combine 2 important functions in one shell: now you can calculate and create 2D graphics at the same time. All you need to get a new version of the program is to download Matkad torrent on the website.

Full list of features:

Increased convenience. Directly in the process of calculations, the equations do not break off at the boundary, but are transferred to next line in compliance with all rules. You can set transfer points yourself or trust the system.
Instant visualization of engineering calculations. Comprehensive plotting software captures engineering data on the fly, so you don't have to wait to build a 2D model.
Modern creation of 2D graphics. Flexible setup 2D charts and graphs provides comfortable work with a visual component. Each schedule is customizable to specific needs.
Data privacy. Engineering calculations are a valuable resource, access to which should be limited. The software sets access levels by displaying certain users permitted information.
Compatible with other applications. Old projects or projects created in other software are transferred in a few clicks. You no longer have to constantly switch between applications and coordinate other users. In addition, all areas are copied into MSWord, allowing you to create reports.

In this section you will find free examples problem solving and laboratory work performed using the Mathcad package. Use these examples or order your work to professionals.

If you want to download Matkad Russian version, which we also have, you can do it here.

Need version smaller in size and which can be launched from any media?

The portable version of MathCad does not require installation, you can use it on any device, run the project immediately from a flash drive or other storage media. The Russian-language interface allows you to quickly master the program.

First of all, I welcome the first visitors to my blog. This is my first article on Habré and I hope that I can tell you a lot of useful things here.

RTS Mathcad is a typical example of mathematical software designed to carry out both numerical and analytical calculations using formulas and visualize their results in the form of graphs. For recent years Mathcad has become very popular, and, in my opinion, it can rightfully be considered the number 1 mathematical package in the world.

First, a few facts about Mathcad, of course, known to most readers, because... We have been using Mathcad for decades in university education, scientific and engineering calculations. Most likely, you used the “old” version of Mathcad (the latest one is number 15), which has changed little since the last century. Nowadays, it quite successfully coexists with the younger Mathcad family, which goes by the name Mathcad Prime. Thus, the developers completely rewrote the program code several years ago, but did not care about 100% compatibility. Therefore, now they safely support both families - both the “old” Mathcad and the “new” Mathcad Prime. Further, both in this article and in my blog, we will talk specifically about Mathcad Prime.

I’ll say right away that you can download the Russian-language distribution, a fully functional 30-day version of Mathcad Prime from the website of the Russian reseller RTS. If you are already planning to try it out, my advice is to take your time in the Setup Wizard to agree to enable a 30-day test period. The fact is that Mathcad Prime, along with the powerful full-featured version (the window of which you see above), has a free limited version called Mathcad Express. The peculiarity of Mathcad Express is that most of the functions in this version are disabled and are inaccessible. However, in Mathcad program Express remains quite rich in functionality, sufficient for at least, in order to study mathematics at school and in the 1st year of a technical university.

Formulas can be entered into documents either from the keyboard (if there are suitable symbols on it) or using the menu Mathematics. For the sake of an example, let's calculate the integral of the function cos(x). To do this, select the integral symbol, and then enter (from the keyboard) the limits of integration and the integrand function cos(x) into the appropriate placeholders. All you have to do is press the “equals” key to immediately get the answer.

We need to have a good idea of what happens when we introduce the equal sign. Namely, the corresponding numerical algorithm for calculating the integral is launched: the integration interval is divided into a certain number of segments, at certain points of which an array of values is calculated integrand function, which is then recalculated into the corresponding approximation of the integral sum. Thus, most of the calculations are hidden and happen behind the scenes, and only the final result is displayed on the screen.

The key tools of Mathcad are operators and functions. For example, in our calculations we used the integration operator and the cosine function. It is convenient to use the menu to select the desired built-in function Functions.

Let's now define custom function f(t), which will depend on the variable t. We will use the assignment operator intended for this in Mathcad (colon with an equal sign).

We defined the function f(t) as our integral of cos(x) with a variable upper limit t. After we have defined the function f(t), we can calculate its values in points (to do this, just enter an argument and press the “equals” key to display the answer in the document). To enter a constant, such as π, use the or menu Symbols, or menu Constants.

You can use not only a scalar, but also a vector variable as an argument. It can be defined like this:

Then the result of calculating the function will be the corresponding vector.

Finally, one of the important features of Mathcad Express is the ability to create graphs in the document. Let's select a place in the document and insert an XY graph (i.e. Cartesian graph) of our function f(x) into this place.

We denote on the abscissa axis the name of the variable z (so as not to confuse it with the previously used x and t), and on the ordinate axis the name of the function f(z), a function that, as you remember, we defined as the integral of the cosine, equal to finitely , sin(z). As a result, we get a graph of this function.

I will also say that in Mathcad Express (perhaps due to an oversight by the developer) matrix operations remain available. Therefore Mathcad Express is quite powerful tool for solving linear algebra problems.

By moving up and down through the document, we can view our calculations, and we can manage them using the menu Calculation. By default, the automatic calculation option is enabled (as you enter formulas into the document, these formulas are immediately calculated). If this option is disabled, then in order to calculate the document manually, just press the button Calculate.

Let me stop here, believing that the task of introducing the reader to Mathcad Express has been solved, and in the following blog articles, when we'll talk, actually, about mathematics, I will be able to use calculations in Mathcad without delving into its interface.

In conclusion, I direct the interested reader to my video course on mathematical analysis, which was held in the MOOC format on the INTUIT portal in 2014. All laboratory works made in Mathcad Prime and you can download them. All these materials on the Nerepetitor.ru website are free, registration is not required.

PS. To my surprise, having encountered several negative comments, I will also note several shortcomings of Mathcad (again, from my point of view):

only Windows version available
resource-intensive, works slower than “previous” Mathcad
the interface could be more convenient
You cannot save a document in the previous version (for example, from the 3rd version in the 2nd format)
documents from “past” Mathcad cannot always be imported into Prime
