The first optimization is to re-order the loops to enforce local access in all of the matrices. The standard mapping was then used from a two-dimensional array onto a one-dimensional space. This makes explicit the fact that subscripting in a two-dimensional array requires integer multiplication as well as addition. Replacing subscripting with explicit pointer access allows the elimination of these multiplications.";
