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.

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.

They talk about us (all reviews...)

  • The best software for Engineers. Easy, lightweight and comprehensive. Kudos to its Developer.

    by Shafiq

  • Smath is easy to use tool and its is freeware.I used for engineering calculations instead of easing excel. Its a time saver.

    by Naresh varikuntla

  • I'm a student of civil engineering and SMath has become an invaluable tool for "by hand" calculations of my assignments. I can't believe other students are still using MS Word and a regular calculator.

    by Filda

  • Great instrument. Thanks

    by Antonio Fazzutti

  • Excellent tool...

    by Munawar Jakhro

  • 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

  • Dentro del ámbito de la investigación y desarrollo electrónico es una herramienta completa para realizar los análisis preliminares y más. / Within the field of electronic research and development, it is a complete tool for preliminary analysis and more.

    by Cristian Matorra

  • Brilliant program. I have MathCAD but as they have gone for subscription based I am discontinuing that. Until now I have not found any design calculation that I cannot make using SMath Studio. I recommend to all of my customers to forget all spread sheet based calculations and go for SMath Studio. I have developed my own specialty engineering software and know how much work that is. Thank You Andrey.

    by Jouko Tolonen

  • Thank you for SMath. It's been a life saver.

    by Bob Johansson P.Eng.

  • 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

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.

Hi Andrey!

Problems with Formatted Label.
Apparently, it occurs when both text and background color is specified with "light ..." as shown.

To overcome this issue you need to remove spaces from color name (" "). I will fix this.

In the meantime I've added a workaround in the plugin.

Cleaning "~/.config/SMath" directory and reinstalling all plugins solved the performance issue.
Possibly would be resulted same with cleaning the "Roaming/SMath" directory under Windows.

In the meantime I've added a workaround in the plugin.

This workaround will not work.
You need to change line
Code:
SMath.Drawing.Graphics.GetColorByName(color.Replace(" ",""));

with
Code:
SMath.Drawing.Graphics.GetColorByName(TermsConverter.DecodeText(color));


This is because variable color contains value from Term where text is always encoded. While GetColorByName does not except encoded values.
In case you want to see an example: I did the same correction in the Plot Region plug-in in my latest commit in main repo.

Best regards.

Sorry about the late reply.

When I open a selection box by holding the left click, it gets stucked, so I can't select objects and move them around.

I can select objects by clicking but can't drag them.

I'm testing right now and it happens only in worsheets created in previous versions.

Problem is as shown in post #13.
It occurs for files created in latest SS also.

Did another clean-reinstallation.
Now the problem is solved only for new files saved in 99.7792.
But not for previous versions.

Thank you.

Do you mean for documents created in previous versions ?
As far back to previous versions ?
As well I noticed that last version affects "0.98.6179.21440"
Roots (range) options => Can't be set anymore ± 2.5
... Takes integers only or set it back to integer.
That happened from downloading some Forum latest version
even if denied updating like usual !
Take care ... Jean

If you open the SMath file with a text editor, the second line shows the version:
e. g. <?application progid="SMath Studio Desktop" version="0.99.7778.42164"?>

if you can run the worksheet, just use appVersion(-digits), the negative values are for the worksheet version while the positive are for the executable.
