Textbook Numerical Mathematics and Computing fifth edition, by W. Cheney and D. Kincaid. Available from Pitt Bookstore.

Content This course is an introduction to numerical linear algebra which addresses numerical methods for solving linear algebraic systems and matrix eigenvalue problems and applications to partial differential equations. Although the course will stress a computational viewpoint, analysis of the convergences and stability of the algorithms will be investigated. We will cover the following chapters in the textbook: systems of linear equations, ordinary differential equations, least-squares method, boundary value problem, partial differential equations and minimization of functions.

Grading Policy The final grade will be based on homeworks (40%), and exams (60%). Late homework will be accepted only by special permission of the instructor.
