  • luce muy bueno el programa, demasiado útil, una potente herramienta de calculo de uso libre

    by IVAN KALLATA

  • 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

  • I strongly encourage professionals who use the software for commercial purpose to donate. SMath Studio, in my opinion, is better suited for documenting engineering calculations than MathCAD Prime 3, which is commercially developed, and is considered to be the software of choice by many. As engineering professionals, we all pay yearly professional license fee; if we donate a fraction of that fee to Andrey it will let him to continue working on this extremely useful and functional tool. Thank you, Andrey! Long Live SMath

  • Excellent alternative to MathCad and it's free!

    by Marco Finlay

  • I just discovered this project and WOW!: What a great alternative to MathCAD. I encourage engineers and scientists to try this app, you will be amazed by its power and versatility. Thanks to developers!

    by Diego Nacif

  • trop bien ce programme....pour faire de fiches de calcul. en plus on peut ouvrir des fiches Mathcad sans souci aucun.

    by aedes

  • Спасибо вам за вашу работу, это приложение просто прекрасно!

    by Илья

  • SMath Studio is an excellent free tool that can be used by anyone ranging from students to professionals. I have used it since back in college, and it has been an invaluable tool for speeding up my productivity and design quality both in my work and hobby life. Thank you Andrey!

    by William

  • I really like it. It's one of the most usable free software applications I deal with.

    by Juanma Belda

  • 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.

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.
Screenshot: description is edited -> a second cursor appears in input data

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.
