Maybe you should look at SymPy. They have some (although limited)
support for symbolic matrix expressions and computations.

SymPy documentation:

 http://docs.sympy.org/0.7.2/modules/matrices/expressions.html
 http://docs.sympy.org/0.7.2/modules/matrices/immutablematrices.html

And various Blog posts:

Hope this helps.
