The main points of the lecture were
- Singular Value Decomposition
Goals:
After this lecture you should:
- Know how to use singular value decomposition to solve systems of
equations, and to compress data.
Reading
- The class notes and Ch. 6 of Kahaner.
Question of the Day:
- Due to roundoff errors, matrices are never perfectly singular. How can we
use singular value decomposition in an algorithm to get "good" answers to such
nearly singular problems?
