Matrix Multiplication: a Visual Guide
Matrix multiplication is weird. It’s kind of basic but then again not. If you know how to multiply matrices then you probably know how to perform this row-times-column scheme to get the result. But what does it actually mean? What are we doing when we multiply some matrices and how can we interpret the process? In this post, we’re going to delve a bit into that. We’ll have a look at the visual representation of matrix multiplication and how we can think about the row-times-column process in more abstract terms.
But before that, let’s have a look at the basics.
