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.
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.

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.

I have used MathCAD since 1997. Loved it. I used to work for the Nuclear Industry in Canada, and we had these long calculation sheets fully written in MathCAD. As an independent researcher, I also had a student version which I could simply purchase from a campus bookstore as a CD. A few years later, disaster struck! A greedy corporate entity purchased MathCAD and destroyed it. A tool created for engineers by engineers with engineering in mind was destroyed by MBAs with only money in their minds. I was helpless until I discovered SMath. I was amazed at how SMath could do so many things with the installation file being just a few MB! And Andrey simply gave it away to us for free!! SMath has truly filled the void left by the now-extinct "old MathCAD". The fact that SMath is not bloatware and gives us researchers exactly what we need are reasons enough to call Andrey a genius. My dear Andrey, many of us are out there in various parts of the world quietly blessing you for helping us do our research calculations. You are a noble soul with a spirit that cares for a better world. Trust me, you have in your own way made our world a better place to live through SMath. God bless you. I shall surely donate an amount as a symbolic gesture for your great work. Please continue to serve the world and may God bless you with good health, a long life, peace, prosperity, and a sound mind that scientifically contributes for as long as you live and pave the way for your glorious legacy long after we are all gone.

The behaviour of loops with second value seems to have improved. Is this generally fixed or just by chance? ![2018-03-26 22_29_20-SMath Studio - [Matrices.sm_].png](/forum/resource.ashx?a=22617&b=2) |

Discovered following behaviour concerning pagebrakes with very long blocks: (scroll to right if necessary)  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

Screenshot: description is edited - 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.

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. |

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.

There is one known shadow in context To avoid "shadow in the context" I uploaded a very clean sheet (#7) which shows exactly the behaviour I described. Originally Posted by: Jean Giraud

Really don't know why I should want to define 'if' myself.
