Complex Matrices


Here is my problem: I have a matrix, M , with complex elements, and I want
to find M*.M. If I try Conjugate[ M ].M. or Conjugate[ M[[1,1]] ] M[[1,1]],
Mathematica will not expand the answer.That is to say instead of having
all of the I's replaced with -I's, I just get back Conjugate[ M ].M. even
if I try Expand[].  Which is not a lot of help.
