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.

Niezwykle przejrzyste narzędzie. Świetne do sprawdzenia czegoś na szybko, naturalne jak pisanie w zeszycie. Silna alternatywa dla MathCADa, zdecydowanie godny polecenia!

BTW: Interrupt on error is very handy - allows to break further Worksheet calculation if anything goes wrong. May really simplify work with large documents.  Use Ctrl+Mouse Wheel to play with Multiple Pages feature.   Edited by user 12 February 2019 18:56:09(UTC)

В последних версиях заметил такую особенность: когда подгружено много плагинов программа задумывается при вызове доступных функций (вроде как начинает просматривать что есть и поэтому всё зависает на несколько секунд), да и при дальнейшей работе в окне все довольно не быстро. В старых версиях тормозов замечено не было. Небольшое кино: нажать тутСо стандартными функциями работает все быстро. Можно как то оптимизировать? Edited by user 12 February 2019 21:40:31(UTC)

Для начала убрать лишние плагины. Очень много функций в DISLIN, которым пока не имеет смысла пользоваться. Также можно убрать Matlab и Octave плагины, если используется 64-битная версия программы. EFI плагин нужен только для поддержки старых Mathcad'овских библиотек. Он тоже не нужен скорее всего. NumPlugin - это просто пример плагина, так же как и VBNetPlugin. Они не нужны.

Поправил. Теперь диалог работает моментально вне зависимости от того, сколько плагинов установлено.
