### All About Matricies ....

This is an introduction to matricies.

You can review the basic operations (addition, subtration, scalar multiplication) on matricies here.

Learn about matrix multiplication there.

You can also watch two movies about Transition Matricies. (You might need to download the Quicktime Player; you can get it (free) here.) The first one explains the mechanics of what they are and how they work. The second movie takes you through two different examples, slowly and carefully, showing how to solve transition matrix problems. Something I haven't yet mentioned in class; transition matrix problems are also called
