MATLAB: Symbolic Math Toolbox not working on Windows 10 Matlab R2019b

Question

I've install the SMT and Matlab indicates licence is present and working. However, it get error:

Error in maxtrix_algebra (line 5)

syms x

So it doesnt even start, what is wrong with this?

Answer 1

Well in fact i have to type in

restoredefaultpath

every time i start Matlab to avoid this error. So i just put this line in the script.

many thanks,

Neil
