Elementary Numerical Analysis: Algorithmic Approach by Samuel D. Conte English | 1 May 1980 | ISBN: 0070124477 | 408 Pages | PDF | 4 MB
This is old but good. It has a similar concept to "Numerical Recipes" by Press, et. al. but covers less ground, and at a more elementary level. Contrary to another reviewer, it does give plenty of examples at an elementary level, which I find quite helpful.
Numerical Analysis in Modern Scientific Computing: An Introduction, Second Edition By Peter Deuflhard, Andreas Hohmann English | PDF | 2003 | 350 Pages | ISBN : 1441929908 | 24.83 MB
This introductory book directs the reader to a selection of useful elementary numerical algorithms on a reasonably sound theoretical basis, built up within the text. The primary aim is to develop algorithmic thinking-emphasizing long-living computational concepts over fast changing software issues.
