SMath Studio

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.

Très bon logiciel de calcul, avec de nombreux plugin pour tous les usages. Une fois qu'on s'habitue, on ne peut plus s'en passer. Je le recommande vivement. Outre les fonction mathématiques, Il est possible d'utiliser de nombreuses bibliothèques, comme par exemple la bibliothèque Coolprop pour les données thermodynamiques, ce qui permet d'avoir un outil très évolué pour faire et expliquer des calculs très rapidement.

Great free software! I am enjoying watching its progress and use every day for reinforced concrete calculations and client presentations! Hope it gorows well"

I needed the simplest functions, which I did in Mathcad. Now this software does everything I need. Keep up the good work. Brilliant. Thank you.

If you are thinking about getting MathCAD for your business or personal use you may want to try SMath Studio first. SMath Studio is a free math program with easy to use intuitive "paper-like" interface. If SMath Studio meets your needs then look no further and consider donating to promote further development of this great program. On the SMath Studio forum, the developer and forum community are very receptive to help questions, bug reports, and feature requests.

Best WYSYWIG math software, with outstanding cost/effect factor! In some areas even better thought than it's commercial oponent (auto complete, very big plugin database, small program size etc). Highly reccomended.

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!

Extremely powerful small app. You get the most of the MathCAD functionality for free. As an engineer I use this app on a regular base.

This is an excellent software for methodically solving/performing strenous formulas/calculations. It is an incredible inspiration that it is free !
