Introductory Linear Algebra TechCompanion

These pages contain some simple MATLAB computations and graphics which supplement the text and lectures for introductory linear algebra. (Most of the code is usable verbatim in the free, open source system Octave.) There's not much here yet (as of Sept. 2019)... but I hope to add more. Feel free to send me errata and/or other feedback at smyth@cooper.edu.

For a much more detailed introduction to MATLAB (and other computer algebra systems) see my Calc 1 TechCompanion, or an online tutorial.
