Re: Symbolic matrix operations

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!
