Hi there,
My "Exterior Differential Calculus and Symbolic Matrix Algebra" package
(http://www.inp.demokritos.gr/~sbonano/EDC/), allows the user to define
arbitrary symbols (like A, B) that will be treated as matrices. The package
uses the symbol "[Wedge]" for matrix multiplication, and contains definitions
for symbolic application of Transpose, trace and the Cayley-Hamilton theorem (see examples in EDC_Manual.nb and in matrixEDCexamples.nb).
Good luck!
