Then, my brain got stuck on using DOT to compute the sum of the products of the factors. The problem with this method is getting the result of FACTORS split into two vectors, which I haven't found a good way to do. This is what I ended up with for a "general form" of the problem: Code: FACTORS I'm sure there's simpler methods.
