Propblem with integration with constants

How can I integrate somehow that integration constants appear?

For example MATLAB prints: int(x)=1/2*x^2

Since I need it to be; int(x)=1/2*x^2+C

According to ‘Tips’ at the end of the documentation for ‘int’:

Results returned by int do not include integration constants.
