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.

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.
