A very brief introduction or review on linear algebra for data science.

Several of my classes, especially Recommender Systems, make use of linear algebra concepts and notation. This document collects some basic notes on linear algebra concepts and what they mean to act as quick crash course or refresher, along with pointers for further study.

This document is relatively terse; for a more in-depth treatment, see the resources at the end of the page, particularly Linear Algebra Done Right.
