SMath Studio - SMath
Created by SMath LLC in the scope of SMath project. Published by smath.

SMath Studio

  • SMath Studio box
  • Calculation of Gravitation Acceleration example
  • Example of animation on the Worksheet
  • Extensions Manager tool
  • Opened math Reference Book
  • SMath Viewer output to Autocad example
  • SMath Studio on iOS
  • SMath Studio on iPad

Tiny, but powerful mathematical program with WYSIWYG editor and complete units of measurements support.

It provides numerous computing features and rich user interface translated into about 40 different languages. Application also contains integrated mathematical reference book.

Stable version

Free for personal usage! Plans for Organizations are available!

Application can be easily extended based on your needs. Built-in Extensions Manager tool allows to get access to hundreds official and third-party resources of the following types: usage examples, plug-ins, SMath Viewer based applications, snippets, interface translations, interactive books, handbooks and tutorials.

  • As experienced mechanical guy, this powerful tool is extremely useful for calculation for my work activities, and amazing it is free please keep working for software crown and kick expensive mathcad away!

    by Kelvin Liu

  • I have been wishing for a sensible alternative to the free version of MathCAD for a long time. I find such software a crucial tool for writing technical-paper-style documents with live formulas and units carried throughout. I am so happy to have found SMath Studio as it is not just a completely free, fully featured alternative, but I find it to be much better in that it is tiny, is easier to use, has nice community support and has nice expandability by others (through plugins). It has features I've always wanted like setting of number of significant digits (not just number of decimal places), easier typing of subscripts, better plotting (via the X-Y Plot plugin), ability to include other SMath files (like my own units definitions), the very innovative and helpful "dynamic assistant", the ability to assign values to variables *after* the writing of a formula, no watermark across each page, and many other improvements that I have yet to discover. Since I am so pleased, I just donated $100 which I feel is a more reasonable amount for software like this. Thank you, Andrey!

    by John David Heinzmann

  • Thank you Andrey Ivashov for developing this wonderful software, as well as all the people who contribute with solutions day after day. As a university professor, I must say that the use of SMath Studio has contributed greatly to improve the way of transmitting and sharing knowledge.

    by Eduardo Palma Zambrano

  • Probably the best free math program out there. As a mechanical engineering student, so many calculations can be almost entirely automated using SMath Studio.

    by Bellus

  • Alternativa gratuita fantastica a MathCAD ! This is a fantastic free alternative to Mathcad, strongly recommended to anyone dealing with engineering and calculus.

    by Marco

  • Amazing, well-done, useful tool. A small donation was sent your way. This small comment of praise is a follow-up.

    by Jason H

  • Great tool for all engineers. It's very user-friendly and has lots of functionalities that can be further extended by installing plug-ins (it takes just a few clicks, no need for tedious file manipulations). SMath can operate on units, perform symbolic calculations and many more. Also, it has very clear interface and all formulas can be entered just like you would do on a piece of paper. What's more, the software has great community of people willing to help with various issues.

    by Jacob M.

  • excellent

    by Mohan

  • smath studio. It´s a good tool.

    by jose luis rebollo

  • SMath makes my job as a mechanical engineer easier. It creates much more presentable calculations which are easier to follow (compared to a Matlab script or Excel spreadsheet).

    by Albert

SMath Studio in publications

SMath Studio plug-ins (all plug-ins...)

The functionality of the program can be expanded through the installation of plug-ins created by third-party developers and companies, as well as those prepared by the SMath LLC team. Most plug-ins are open source and can be modified if necessary.

The behaviour of loops with second value seems to have improved. Is this generally fixed or just by chance?

Discovered following behaviour concerning pagebrakes with very long blocks:
(scroll to right if necessary)

Pagebrake.PNG

The red marked block is so long, that it reaches the top of following page.
As you can see in the preview window, the sheet content is not printed.
Page 2 starts after the page brake with "Biegedrillknicken" when "Printing Bounds" is used.
While using "Pages view", the first printed page looks the same (mostly white) but the second page starts with the skipped content "System l=5,00m..."

Setting the font size only of the large block to something smaller so the bottom of it doesn't reach the page brake solves this issue.

Found another issue, while editing the description of a 2D plot:

When you put the cursor in the description and edit the text, a matching variable in the input data is edited simultaneously.

We are here in the "RC2: 0.99.6654"-thread.
So I thought it would be clearly that I refer to 0.99.6654.
Take a look at the video (screen capture) if you don't believe what I am writing.

Your screen shot is explicit enough, but the document would help
more collab to check that particular issue or similar problem.
Nobody reported this bug, if it is an Smath bug.

Can repeat both bugs with the provided file on 6654. Oddly enough I was able to enter a description sometimes without effecting the data field if I first clicked within the data field, then immediately clicked the description field. This only worked occasionally and seemed dependent on where I clicked within the data field.

Bug/NObug ... pretty strange, whatever.
The document attached does not contain
the live Smath part in snippet # 3
There is one known shadow in context
You can't define a function starting with 'if'
if(a,b,x):=fnct(a,b,x) ... if NOT allowed.

Quick tip to get rid of "sometimes without effecting the data field"
1. in the description, type few letters not common to data field
2. once finished the description, zap the fake letters.

To avoid "shadow in the context" I uploaded a very clean sheet (#7) which shows exactly the behaviour I described.

Really don't know why I should want to define 'if' myself.
