Amazon Summary
This is a concise, insightful introduction to the field of numerical linear algebra. The clarity and eloquence of the presentation make it popular with teachers and students alike. The text aims to expand the reader's view of the field and to present standard material in a novel way. All of the most important topics in the field are covered with a fresh perspective, including iterative methods for systems of equations and eigenvalue problems and the underlying principles of conditioning and stability. Presentation is in the form of 40 lectures, which each focus on one or two central ideas. The unity between topics is emphasized throughout, with no risk of getting lost in details and technicalities. The book breaks with tradition by beginning with the QR factorization - an important and fresh idea for students, and the thread that connects most of the algorithms of numerical linear algebra.

that book, i think, is fantastic. i was a TA for a graduate (and undergraduate) level course using it in Urbana-Champaign around 25 years ago. It's just a great book.

Another great "intermediate" textbook (in my opinion) is Trefethen's Numerical Linear Algebra [1]. Much more readable than Golub's I would say, which is more like a reference than a textbook.

This is actually the best book of the lot.

Strongly agree. This was actually the text book when I took numerical methods at MIT. As far as math texts go, it is definitely a joy to read.

Question: is anyone working through Numerical Linear Algebra, or has done so in the past?

I'm having a really tough time with the exercises even though I should have the prereqs... What can I say, we don't do much rigorous math in engineering.

Anyways this book came highly recommended to me from a friend in quantitative finance.
