Iterative methods for sparse linear systems (2nd edition) This is a second edition of a book initially published by PWS in 1996. It is available from SIAM. In this new edition, I revised all chapters by incorporating recent developments, so the book has seen a sizable expansion from the first edition. At the same time I also removed some of the topics that have become less important. A notable addition is a chapter on multigrid techniques. The first edition posted (see below) will remain on my web-site (as is). The table of contents of the new edition can be accessed in: post-script   or   PDF .
A few distinct erratas are available for this book. The first one concerned the first printing of the book (sent to publisher for 2nd printing in 2004). The second was sent to the publisher in May 2007 at the occasion of the 3rd printing. The third errata was contributed by Nicholas Hu (University of British Columbia) in 2020/2021 (Big Thanks!)

Iterative methods for sparse linear systems (1st edition) This book, originally published in 1996 by PWS, is now out of print. PWS (and now ITP) no longer owns the copyright. I revised the manuscript and I am making the post script available for those who want to use it. A new edition of this book is now available from SIAM, see above.

• Compressed (gzip) tar file
• zipped (zip) post-script files
• zipped (zip) PDF files
• Access to all files (compressed and uncompressed) from the ftp directory. Once you download the files you will need to unpack them and you will find 4 separate PDF files (iter1.pdf, iter2.pdf, iter3.pdf, iter4.pdf). You can also get directly the individual PDF or post-script files (fourth of the options given above).
