Tidy up expression after differentiating

The equations I am working with in this problem contain exponentials. For this reason, after differentiating they appear again pretty much unchanged apart from additional constants and other factors. I was wondering if it might be possible to…

OOP: Change of class of object following operation - operations no longer as desired

I am new to Object Oriented Programming. After a lot of stressing, I have finally managed to define my own class of objects in matlab's symbolic engine, muPad. The engine has its own language, the syntax of which is very logical and similar to…

Matlab change in symbolic notation of derivative

I've recently upgraded Matlab from 2013b to 2019a (yes, I know, a lot has changed....but not software costs). I have some "legacy code" which makes heavy use of the symbolic tool box. One thing that seems to be causing a big issue is the change in…

Finding all solutions to a non-linear equation system with MuPAD

My question is if there is a good way to use MuPAD functions in a Matlab script. The background is that I have a problem where I need to find all solutions to a set of non-linear equations. The previous solution was to use solve in Matlab, which…
