Matrix operations on character matrix element?

I hope somebody will be able to help me here.
I am trying to solve some physical problems that will require the generation of some function in terms of some parameters. These functions are derived from matrix operation on “characters”. Are there ways numpy/scipy perform matrix operations on characters?
For example A =  matrix([[a, b,c],[d,e,f],[1,2,3]])   
                          B = matrix([[g,h,4],[I,j,5],[k,l,6]])
Is it possible to perform operations like A*B or A+B
And most especially: linalg.solve(A,eye(3,3))
