# Talk:Linear algebra - software issues

This is an excellent article to illustrate the changes of matrix algorithms and software in reaction to computer hardware changes, through a simple but important matrix algorithm, namely LU decomposition (Gaussian Elimination). Most part of article is easy to follow, and enjoy to read. It is a nice feature to include the actual codes. I have two specific comments:

(1) In the presentation of the steps of the recursive LU algorithm, there are typos.

(2) For the multithread version and Tile version, it would be nice if the authors can

   provide one or two major references so that the reader can go for further details.
