It depends how big is your problem and how accuracy you expect. You can wrote your only integration yourself.  One dimensional is really simple.

You can easily do it without IML  if you know
1. MC method
2. the definition of definite integral

Matlab...........

Try a three dimensional integral to see if it is easy.
