MATLAB: How to evaluate integral with given constant

Question

syms x; f = 'h*x'; h =3; int(sym(f))

My code gives (h*x^2)/2

But I want it to evaluate it for h = 3 and then print the answer

Answer 1

Hi,

change the order of your commands

syms x;
h = 3;
f = h*x;
int(sym(f))

gives:

ans =
(3*x^2)/2

Best regards
