Dear all,
I am trying to use 'matlabFunction' feature to convert a symbolic expression into the function. I used an example, given in a help file:
syms x y
r = sqrt(x^2 + y^2);
ht = matlabFunction(sin(r)/r, cos(r)/r)
However, what I always get, is a error message: Undefined function or variable 'matlabFunction'.
I am sure, Symbolic Math Toolbox is installed, cause in the uninstall menu all of the toolboxed as checked as available.
Any suggestions how to make it working?
Thank you in advance!

If you have the Symbolic Math Toolbox from R2008a or later, you will have matlabFunction.

A couple of people have reported this in the past for R2016a. The solution appears to be to reinstall the Symbolic Toolbox
