MATlab wont do integrate command
显示 更早的评论
Matlab only gives errors when the script is:
int(x)
%or
int(x,x)
%or
int(x+5,x)
I just want to get answers such as .5x^2, or .5x^2+5x.
The error is: Undefined function 'int' for input arguments of type 'double'.
I have Symbolic Math Toolbox Version8.2 (R2018b) running

You have to first initialize x as a symbolic variable. You can find more information and examples here.
syms x
f = .5*x^2
int(f)
