Does anyone know how to perform symbolic matrix operations in mathematica without computing on the element level? For example, if I need to expand (AB)^T and get the result in the form B^T A^T, what should I type? I am trying to find a way to simplify matrix equations without actually multiplying, transposing, inversing etc matrices on the element level. Thanks. DS
