Unformatted text preview: Numerical Methods Course Notes Version 0.11 (UCSD Math 174, Fall 2004) Steven E.

In writing these notes, it was not my intention to add to the glut of Numerical Analysis texts; they were designed to complement the course text, Numerical Mathematics and Computing, Fourth edition, by Cheney and Kincaid [7]. As such, these notes follow the conventions of that text fairly closely. If you are at all serious about pursuing study of Numerical Analysis, you should consider acquiring that text, or any one of a number of other fine texts by e.g. , Epperson, Hamming, etc. [3, 4, 5]. 3.1 3.2 8.4 3.3 1.4 3.4 1.1 4.2 7.1 10.1 4.3 5.1 5.2 7.2 8.3 8.2 9.1 9.2 9.3 10.2 10.3 Figure 1: The chapter dependency of this text, though some dependencies are weak. Special thanks go to the students of Math 174, 20032004, who suffered through early versions of these notes, which were riddled with (more) errors. Revision History 0.0 Transcription of course notes for Math 174, Fall 2003. 0.1 As used in Math 174, Fall 2004. 0.11 Added material on functional analysis and Orthogonal Least Squares. Todo More homework questions and example problems. Chapter on optimization. Chapters on basic finite difference and finite element methods?
