Welcome

Welcome to the website for Andrilli, Hecker: Elementary Linear Algebra, 4th Edition.

The following are several additional "virtual" sections of the textbook available only on this website. They can be downloaded and used to supplement the core material in the textbook itself. We expect to add more of these web-sections in the future, providing further applications, expansions of topics already in the text, and some theoretical topics beyond the scope of the textbook.

The authors may be contacted at andrilli@lasalle.edu and dhecker@sju.edu.
