Hi DS, As far as I know, Mathematica does not have any native support for noncommutative algebras (such as matrices). When I've had to deal with such things, I construct a new multiplication (based on, say CenterDot) and give Mathematica the relevant rules. If you only want to work with relatively simple expressions this is probably (powerful and quick) enough... A group at UCSD has developed a package, but I've never played with it.... (now put that on my to do list!) http://math.ucsd.edu/~ncalg/ OR http://library.wolfram.com/infocenter/MathSource/4594/ It seems to have everything you want (but is a bit old...) The appendix of this thesis http://theses.library.uwa.edu.au/adt-WU2007.0179/ also has some noncommutative algebra using Mathematica... Simon
