1. Fundamentals – (A) Matrices and Linear Algebra

by pheris

The Khan Academy has a basic, high-school-level, interactive matrices tutorial, but I would recommend their college-level linear algebra tutorials:

  1. Vectors and Spaces
  2. Matrix Transformations
  3. Alternate Bases

It is especially useful to be familiar with eigenvalues, eigenvectors, and eigenvectors.
