I have been learning NumPy arrays/matrices in Python. As I worked, I found that I desired a more readable form of 3d matrices. So I figured that writing one would be a good goal and learning exercise. The goal was to create a function that would print 3d NumPy matrices … |

Optimizing Matrix Multiplication One time consuming task is multiplying large matrices. In this post we'll look at ways to improve the speed of this process. We'll be using a square matrix, but with simple modifications the code can be adapted to any type of matrix. The straight forward way to …

Here is a small--complete--program that includes a sub-routine that inputs two matrices and then multiplies them. Notes: * 1) I happen to like taking input from a text file. It eliminates the need to type input from the console, especially when debugging, it prevents the possibility of making typos. * …
