I don't get this

global Kp;
>> Kp=5
Kp =
5
>> global e ;
>> e = 2;
>> func = Kp*e
func =
10
>> q= int(Kp*e, e, 0, 2)
??? Undefined function or method 'int' for input arguments of type 'double'.

In the future, you might want to give your questions a more meaningful title.

int() is a function from the symbolic toolbox, that applies only to symbolic expressions (or character strings that represent symbolic expressions.) I suggest trying
syms e
q = int(Kp*e, e, 0, 2)
