I'm unsure how to evaluate a given function at a given point X. Hypothetically, the user can input any function using any letter as a desired variable. How can I evaluate the function at the initial point given. I was thinking I could use the syms command. However, I'm unsure of what letter variable they would use. For instance, if the function was x+1 vs y+1, how can I ensure that the "initialX" is evaluated in place of x or y in the given function?
function y = randFunc(initialX, func)
y = func(initialX);
display(y);

In this case if func is given in the form of a symbolic expression, then use matlabFunction() to turn it into a function handle.
