Does anybody know of a package of functions and operators that can deal with partitioned matrices? Example: mat_a = [ a b ] mat_b = [ d c ] [ c d ] [ b a ] where a, b, c, d are matrices (although not necessarily defined) of appropriate dimensions. Then I can do MULT[mat_a,mat_b] and get mat_c = [ a d + b b a c + b a ] [ c d + d b c c + d a ] without any attempt of changing the order in the products defining the elements of mat_c, because they are matrices, obviously. I already explored the wolfram web site and didn't find anything.
