From the preface of Linear Algebra and its Applications:
“Linear algebra is a fantastic subject. On the one hand
it is clean and beautiful.” – Gilbert Strang
This wonderful branch of mathematics is both beautiful and use-
ful. It is the cornerstone upon which signal and image processing
is built. This short chapter can not be a comprehensive survey
of linear algebra it is meant only as a brief introduction and re-
view. The ideas and presentation order are modeled after Strang’s
highly recommended Linear Algebra and its Applications.
