This is an amazing mathematical tool which is at the same level as some of the most sophisticated and expensive math software. I use it in all my classes and promote its use with all my engineering students.

by Antonio Medrano
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.

by Bartłomiej Minor
Amazing math tool. I use it almost daily. I'm a civil engineer and Smath Studio quickly became one of my favorite tools to "hand check" a lot of my calculations.

by Fernando Siedschlag
Powerful tools to support dynamic calculation. Excellent!

ein absolutes Muß für Ingenieure und Naturwissenschaftler und die, die es noch werden wollen. Ein perfektes Tool für Hochschulen aller Art. an absolute must for engineers and natural scientists and those who want to become one. A perfect tool for universities of all kinds.

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

by Igor Skarine
Andrey has given us back the joy of Math that we experimented with Mathcad some thirty years ago, until PTC messed it all up. A fantastic achievement! And free! I am beginning to use it intensively to help my engineering students.

by Manuel Vargas
The best software for Engineers. Easy, lightweight and comprehensive. Kudos to its Developer.

Objectively all should be transparent. Am I right/wrong ... don't want to damage 6179 !!! Thanks, Jean

In this case, your installation is updated (you may also need to update some plugins). To try the new version without harming your existing one, use the portable version (see my signature for a link) as a sandbox. You simply unzip the archive anywhere and run the SMath exe in the new directory. If you like this version, you can declare it as default application for .sm file using context menu in the file manager (Open with...).

ComboBoxRegion puts the assigned variable (aka the result) into a matrix. Other functions which use this variable then throw an error because you are trying to use a vector as opposed to a scalar. 2. Include and areas - Include will not include variables inside of an area. Are these statements above correct?

Reason being - "Genfit Algo Include" is inside an "Area Region". I tried to download an older stable SMath version, but I still have issues with Comobox plug-in. Is there a Combobox plug-in page I should post on? I'm not sure if it is a revision in the plug-in or the updated SMath.

I meant to reference the ComboBoxList (insert -> controls -> ComboBoxList). There must have been a change when using "Output = item's row". When I had used a column vector it would return the output as scalar. Not it returns it as in a matrix. This actually makes sense. I should change my sheets that that "Output = n-th element in the row", this would give me a scalar result. Edited by user 12 October 2017 05:11:32(UTC) \| Reason: Not specified

When updating/reusing a sheet, I delete the variable information to update the sheet. Depending on what is going on, the auto recalculate with "crash" the program and re-start. Right now I just will in the number 1 as I gather the information. Hidden regions cause a huge issue when cutting and moving when collapsed. I need to open up the hidden areas in order to move them.

Set it to 0 to not have this behavior. Originally Posted by: mkraska However, if I open your sm file, the numbers are displayed correctly. If you mean that you can read "126". that's strange; I'll look if might be some localization issue.
