a guide or manual for matlab Function?

Apparently it's the answer for me since I can not use the symbolic math toolbox but I do not use matlabFunction on the page https://www.mathworks.com/help/symbolic/functionlist.html I do not understand it. Any manual or guide how use it? I want to use it to declare a symbolic variable is that I need to print a polynomial and so you will need to show variables. I'm making a guide that will be executable

matlabFunction is not useful to you in this circumstance. Your input function is from the user, not something that you could pre-convert into MATLAB code to be compiled.

matlabFunction itself is part of the Symbolic Toolbox and so cannot be compiled.

damn it, any alternative?
