This page will get you to some documents, including my Linear Algebra text. It also has information about my classes, and how to reach me.
I have an undergraduate text Linear Algebra. It is free, including the PDF, LaTeX source code, in-class beamer slides, and lab manual.
I'm also having a lot of fun with Logic, Python, Scheme, and ham radio. (I'm KE1AZ by the way. CW QSO?) And, jogging.

Office hours: MW 2:30-3:15, Tu 2-3.
I have a text available for download. It covers the material in a standard course, in a developmental way. Have a look.
This book is also available free for downloading. It covers a first course, and is based on a writeup by W Edwin Clark, of the University of South Florida. It also comes with LaTeX source. (Note. This book is rougher than the Linear Algebra above. Prof Clark has written a brief and beautiful book. However, my revision is still lacking in some areas, for instance in exercises. Nonetheless, I have used it here at St Michael's, in an introductory course for majors that contained nonmajors who did well.)
I intend to write some more in the same style when I get a chance. (if someone sends me mail telling me how great this one is, that would be an inducement!).
