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.-From the preface of Linear Algebra and its Applications:
