I've been surprised and disappointed to discover just how primitive matlab's handling is of ND symbolic arrays. Surely it shouldn't be difficult extend mupad so that it can handle ND multiplication? Also on a related note, it's very disappointing that bsxfun doesn't handle symbolic variables. Is this extension going to be added in a future version?

I note that in Maple, array multiplication beyond 2 dimensions is handled as element-by-element multiplication, not as some kind of Matrix Multiplication.
Note that Wikipedia defines matrix multiplication only for two-dimensional matrices; see http://en.wikipedia.org/wiki/Matrix_multiplication#Matrix_product_.28two_matrices.29
