Because the matrix multiplication is associative; the product can be carried with different order, leading to the same result up to round-off error, MMTIMES usings "optimal" order of binary product to reduce the computational effort (probably accuracy is also improved)

The function assumes the cost of the product of (m x n) with (n x p) matrices is (m*n*p). This assumption is typically true for full matrix.
