Linear Algebra @BUCS
UNDER CONSTRUCTION
This is a (very early draft) set of notes for CAS CS 132: Geometric Algorithms at Boston University. Admittedly, I was unsure if I wanted to take on this project (in a sense, I still am). I'm not convinced there's a need for another collection of notes on linear algebra. But it turns out I can't help myself. I am of the opinion that any good course needs to be personal, so these are my personal notes, which follow my way of thinking about and organizing the material. It's also my excuse to play around with building visualizations (all of which are pretty much hand-spun using Elm).
These notes are based heavily on Linear Algebra, Geometry, and Computation by Mark Crovella, which are in turn based heavily on Linear Algebra and Its Applications by David C. Lay, Judy J. McDonald, and Steven R. Lay (a mainstay in undergraduate texts on linear algebra).
