It also depends on instruction mix. Your processor will have several computation units standing by at any time, and you’ll get maximum throughput if all of them are filled all the time. So, executing a loop of mul’s is just as fast as executing a loop or adds – but the same doesn’t hold if … Read more
If the matrix A has more rows than columns, then you should use least squares fit. If the matrix A has fewer rows than columns, then you should perform singular value decomposition. Each algorithm does the best it can to give you a solution by using assumptions. Here’s a link that shows how to use … Read more
