M313 Linear Algebra
Table of Contents
There will be no lectures on Friday 1/27, Monday 1/30, or Friday 2/3. There will be class on Wednesday 2/1 at the usual time.
There are four sets of videos for these days. Each one will have an associated gradescope assignment. The videos are posted now, but the assignments are staggered.
If you have questions, you are welcome to email me. I also recommend stopping by the Math department's free tutoring service, which is offered daily in Math 220. A schedule is available here.

The LDU factorization is not covered very well in Lay. Although I discussed it in lecture and it will be on the homework, it will not be included in any exams.
