[Note: some of these topics (and many of these links) will change, reflecting updates, improvements, and adaptation to the interests of this year's students.]

Description
Readings
Assignments
1. 9/12++ Overview & organization

Mathematical background
Basic: Eero Simoncelli, "Geometric Review of Linear Algebra"
Michael Jordan, "An Introduction to Linear Algebra..."
Intermediate: Connected Curriculum Project linear algebra materials
Advanced: Desmond Fearnley-Sander "Hermann Grassman and the Creation of Linear Algebra"
Stephen Gull et al. "Imaginary Numbers are not Real"
(Note that these describe types of linear algebra significantly different from those that will be used in this course. They are offered as enrichment for any students to whom standard linear algebra is old news.)
Placement test, to be completed in class.

If you miss the first class, please fill this out and return to Laurel Sweeney at IRCS.

Instructions: there are 20 questions whose answers should be obvious if you know and remember the material, and impossible otherwise. Don't spend more than 10 minutes on it. If you don't know the answer to a question, leave it blank rather than guessing.We don't expect you to know all this materials, or even a majority of it. The point is to give us a sense of who needs (or doesn't need) help with what.
