Web17 aug. 2015 · Right now the matrices are small, and if that stays the same don't mind this point, but if you think they're going to get larger you may want to look into tiling the multiplication - this will have much better caching behavior than a large row-major x row-major multiplication. As-is, with matrices of this size, unless you're doing a ton of them ... WebMatrix multiplication is not universally commutative for nonscalar inputs. That is, A*B is typically not equal to B*A. If at least one input is scalar, then A*B is equivalent to A.*B and is commutative. C = mtimes (A,B) is an alternative way to execute A*B, but is rarely used.
