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.

  • This tool is amazing. It helped me on my university more times than i can imagine.

    by Radek

  • 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

  • This has been a great step up from Excel. Extensive (and extensible) support for engineering units opens a new world for well documented everyday analysis. Thank you!

    by Mike Graham

  • I hope you keep on developing this great software! Thank you very much, it is easy and very efficient. If someone could help you to bring it closer to a nice text editor, it would probably replace Word for many engineers and other scientists.

    by Dimitris

  • Congratulations!! This software is amazing!! An almost complete substitution for Mathcad!!

    by Hervandil Sant'Anna

  • SMath Studio in the Cloud is ideal to show calculations to my students. They only have to click at the internet hyperlink. Teacher at school of mechanical engineering, bachelor level.

    by Hein van de Vrande

  • smath studio. It´s a good tool.

    by jose luis rebollo

  • As a civil engineer, over the years I have frequently used MathCAD for not only performing but also documenting calculations. With PTC dropping perpetual licensing, my recommendation to all the junior engineers I train is to give SMath Studio a serious look. While not a turnkey replacement for MathCAD, it provides most of the functionality and power at an incredible price. Already a wonderful program filling a key niche spot between a numerical calculator like Octave, and a CAS like Maxima, the expanding plugin and 3rd party development is on the rise and this project's future keeps getting even brighter. Much consideration must be given by any engineer or business before they settle on a software for adopting into the workflow. Although not open-source in the strictest sense, the development community is similar to what you would find in any first class OSS software project. The current owner of the SMath Project has also agreed to release the source code under open source license should he not be able to continue the project. So do not let the cost (your time) of learning SMath Studio and migrating your MathCAD computation sheets scare you. This project is here to stay.

  • Excellent tool for electric engineering. Must have portable software on your USB key. Symbolic calculations is a great value for electronics.

    by Igor Skarine

  • Probably the best free math program out there. As an electrical engineer, you can do so many calculations, e.g for designig drive systems and calculate protection settings, can be almost entirely automated using SMath Studio. With the huge amount of plugins you can push SMath in an high level. Thanks a lot!

Hi Andrey,

I see the "Approximately equal" operator accuracy varies from 0 to 15. What does this value actually represent?

Hi! It is an accuracy of the "Approximately equal" operator. F.e. if the accuracy is 0, then pi≈3, if 1, then pi≈3.1, if accuracy is set as 2, then pi≈3.14 etc.

Best regards.

Hi Andrey,
considering that the "accuracy operator" parameter that regulates "approximately equal" is unique, wouldn't it be appropriate that it is defined in percentage terms?

Regarding that.. I think "precision operator" more appropriately reflects the intended purpose.

This is a nice new feature.
Would it be possible to modify this value independent to regions?
Adding another submenu to region right-click would be awesome.
As in decimal places, exponential threshold, rounding choosing.

Hi. About the new approximately equal operator, another way to introduce it could be introducing a general infix operator, like in Mathcad. This screen capture is from Mathcad 6 running in Windows 3.11:

Clipboard02.jpg

For work with units you just need to modify the rhs by abs( a-b ) < UnitsOf( a-b )*TOL (or maybe UoM). Notice that also can be a solution for another features requests, like this one about inline division: https://en.smath.com/for...614_Inline-division.aspx

About the "Defined Integral supports units now" it is a major improvement, and while there will be many worksheets to update, it is a substantial and very welcome improvement. I do think that some kind of special announcement should be made. Also, if you plan to also modify solve and roots to accept drives, you may want to introduce the two improvements together in a future stable beta release.

Finally, many thanks to you Andrey and to all the developers who collaborate with the plugins for this excellent program.

Best regards.
Alvaro.

In the placeholders of the if() function type an "argument separator" symbol (comma or semicolon, usually)

The if without else will improve alot the readability of many scripts, thank you Andrey.

In other words, you declare a bug.
Designers need the document for doctoring.
... doctor since which SS version ?
1.0.8151.26932 OK
1.0.8206.25180 NFG

Yes, I'm reporting a bug. In version 1.0.8151.26932, dimensionless integrals with limits in the form of arbitrary functions are calculated correctly. In version 1.0.8206.25180, such integrals are not evaluated. The error "x/y - undefined" is returned.

It may be the XLS import ?
Try NOT import as a stand alone system.
