## Numerical Linear Algebra, CMSE 823

 Instructor: Mark Iwen Time and Place: Lectures are Tu Th 8:30 am -- 9:50 am, in B104 Wells Hall E-mail: markiwen@math.msu.edu Office: C342 WH Office Hours: Tu 10:00 am -- 11:00 am, and Th 10:00 am -- 11:00 am

This course will cover numerical methods for efficiently solving linear equations and eigenvalue problems. Emphasis will be on the design and analysis of efficient and stable numerical schemes. Students will learn how to solve least squares problems, how to numerically approximate eigenvalues/eigenvectors of matrices, how to compute fundamental matrix factorizations (LDU, SVD, QR, Cholesky, ...), and how to determine the best numerical method to use for doing all of these based on the characteristics of a given linear system (repeated eigenvalues, ill-conditioned systems, etc.). In order to understand why specific methods will or won't work in specific settings, we'll also need some basic knowledge of matrix analysis (e.g., matrix norms, condition numbers, basic perturbation theory).
