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! S.
