Integrate in time domain

I have a function named Kp*e... How do I integrate it in MATLAB say from 0 to 5?

You can use the int(expr,var,a,b) function.

So in your case, it would be

syms e Kp
int(Kp.*e, e, 0,5)

The result would be 25.*Kp/2. You can obviously play around with this by setting Kp to a value, and so on...

 int(Kp*e, e, 0,5)
??? Undefined function or method 'int' for input arguments of type 'double'
This is the error when I do it!

Did you use the line before it? You need syms e Kp fo this to work. (Sets Kp as a symbol). You can also do this for example:

Kp=4.4 % A number I chose
syms e
int(Kp.*e, e, 0,5)
