Linear algebra is extensively utilized in the mathematical modeling of many natural phenomena. Many scientific and engineering disciplines, such as data science, chemical engineering and biology, make extensive use of the theory and techniques commonly present in basic to advanced linear algebra courses. This course will be focused on the theory of vector spaces, inner product spaces, linear transformations, eigenvalues, canonical forms, complex vectors, matrices and orthogonality.
