David Bau (currently at Google) and I published a graduate textbook on numerical linear algebra in 1997. Our aims in this book are beauty, depth of insight, and brevity. The text is split into forty lectures, each about eight pages long. It is based on the course I taught repeatedly at MIT and Cornell during 1984-1997.
The book was published by SIAM in April, 1997, and has been one of SIAM's bestsellers since then.
