Yes, but the second half dealing with iterative algorithms is pretty much useless, especially the chapter on conjugate gradients which is the one most relevant here. There isn't really a book that offers as easy an intro to iterative algorithms as Trefthen does for direct ones. In this case I would recommend to fall back on trusty old Golub and Van Loan (recently released in a new edition).
