Comment #2 on issue 3405 by svhb1...@gmail.com: simplify matrix no return value
http://code.google.com/p/sympy/issues/detail?id=3405

Agree, but the doc string says that the matrix is returned.

So if the matrix is simplified in place (what I consider as the good point), it can be returned with a 'return self' statement. So we are all happy and the implementation is correct with the doc string.

I tested this and it works. The simplify in my example is put into the sequence of operations after observing some very slow operation, and creating huge equations. Simplifying the intermediate results help a lot.

Off topic question: is it possible to 'automatic' simplify equations when doing operations? Look at my own very ugly example in the original post, and you will see what I mean.
