This series of lecturelets is all about matrix analysis. This first lecture is necessary for all the other ones, because it provides important introductions to what can be done with matrices and vectors, how to scale and multiply them, special kinds of matrices, rank and indendence, and other important topics. It is about 50 minutes long (sorry, a bit on the long side).

You'll need this Matlab script.
