** Course description:**

** Textbook **
David C. Lay (with Peter R. Lay, Judi J. McDonald),
Linear Algebra and its applications, Fifth or later edition, Pearson.

The goal of the course is to equip students with basic techniques in linear algebra.
Students are expected to read the textbook, especially, the sections concerning
applications. We can arrange small group discussions for students interested in
specific applications outside classes.
The diescussions may lead to undergraduate research projects.

The course will cover Chapters 1 -- 6 of the textbook, and some additional topics:
singular value decomposition (SVD),
and data compression. If time permits, I will also discuss tensor products
and their applications in data science, AI, and quantum computing.

** Homework **

- Study the practice problems in the books and try some exercises with solutions at the end of the book.
- There will be weekly mandatory homework due on Sunday (11:59 pm) except for
this week and the examination weeks.
- Solution in pdf file should be submitted via blackboard.
- Homework sessions with hints will be conducted on Thursday 2:00 pm.
- Challenging homework problems will be assigned from time to time;

extra-credits will be given to successful (or partially successful)
attempts.
- Additonal extra credit scores will be given to the discussion board for thoughtful/useful comments.
participation related to topics discussed in classes, different ways to understand
the material, and new applications, etc.
