WebJul 2, 2024 · There are several ways to do this. Starting with symfun: syms x f = symfun (x.^2, x); xv = linspace (-10,10,100); f1 = double (f (xv)); This is equivalent to: syms x % or: syms f (x) f (x) = x.^2; xv = linspace (-10,10,100); f1 = double (f (xv)); Alternative is using the subs approach as suggested by Adam.
