Is there a package or procedure for doing symbolic matrix manipulations
in Mathematica?  Specifically, I'm looking for a way to prevent symbols
from commuting, ie (a b) != (b a), and forcing inverse function calls,
inv(a) instead of /a, when solving algebraic equations.  Sub matrix
partitioning would be nice to...

Thanks,
dave
