Textbook
Applied Linear Algebra
by Peter J. Olver and Chehrzad Shakiban. Pearson.
Course Description
Applications and methods of linear algebra emphasizing matrices and systems of equations,
determinants, eigenvectors and eigenvalues. This course is an excellent introduction
to linear algebra for students who are interested in a math minor.
It does not satisfy requirements for the math major.
