Here are my Lectures from Math 221, a Sophomore level linear algebra course which is intended for engineering or other applied technical majors. We're using Thomas Shores' Applied Linear Algebra text, but, I'm likely to supplement with some of my own materials from past teaching of linear algebra.

systems of equations, Gauss Jordan, 1-17-17, part 1 59:51 Note, the excellent webtool I use in this Lecture is found at: http://www.math.odu.edu/~bogacki/cgi-...
