July 30: Midterm 2. 8:10-9 AM. There will be no lecture 9:00-10 AM. The midterm will cover the material from July 10-July 26. To be more precise, it will cover the material from 2.2 (not the part about elementary matrices), 2.3, 2.9 (not the part about coordinate systems), 3.1, 3.2, 5.1, 5.2, 5.3, 5.5, 6.1 (not theorem 3), 6.2, 6.3, 6.4 (not QR factorization), 7.4 (not applications of SVD). I won't ask you to compute a singular value decomposition but I might ask you to do something with a singular value decomposition that I give you.
