How do I convert an anonymous function to a symbolic function in MATLAB?

问题

Say I have a anonymous function f = @(x) x^2 and I want to convert this to a symbolic function. Is there a built in command for that?

回答1:

You could just pass it to SYM:

f = @(x) x^2;
g = sym(f)

But then most of the symbolic functions do that automatically when they receive a function handle (subs, int, etc...)
