4.3 Linear algebra basics

(You can skip this section if you’re already familiar with linear algebra.)

Matrix is all you need to know at this point. This class will focus on mathematical intuitions and let the computer do heavy-lifting computations for us.

If you need a quick refresher, check out this video on matrix:

If you want to dive deeper in linear algebra, start from this intro video and move onto its learning sequence. Again, you don’t need to watch them all and we will introduce mathematical concepts later when necessary.
