Matrix Theory and Linear Algebra is an introduction to linear algebra for students in the first or second year of university. The book contains enough material for a 2-semester course. Major topics of linear algebra are presented in detail, and many applications are given. Although it is not a proof-oriented book, proofs of most important theorems are provided.

Matrix Theory and Linear Algebra in its current form was adapted, thoroughly revised, and extended by Peter Selinger for use at Dalhousie University. It is based on the earlier open text "A first course in linear algebra" by Lyryx Learning, which was in turns an adaptation of the open text "Elementary linear algebra" by Ken Kuttler. Please see inside the book for the full revision history.
Contributors include: Ken Kuttler, Ilijas Farah, Marie-Andrée B. Langlois, Peter Selinger, and the Lyryx Learning Team: Bruce Bauslaugh, Peter Chow, Nathan Friess, Stephanie Keyowski, Claude Laflamme, Martha Laflamme, Jennifer MacKenzie, Tamsyn Murnaghan, Bogdan Sava, Larissa Stone, Ryan Yee, and Ehsun Zahedi.
