Conte S.D., De Boor C. Elementary Numerical Analysis: An Algorithmic Approach

3rd ed. — McGraw-Hill College, 1980. — 445 p. — ISBN: 0070124477, 9780070124479This 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. That is an advantage sometimes if you don't need to wade through all the heavy artillery in "Numerical Recipes". Algorithms are given as pseudocode, and Fortran code which are easily transcribed into any language, such as VBA. I have owned this since 1980 and this is one of the more heavily worn references on my bookshelf. If you just need to quickly understand and code an algorithm, this is a great book to have handy. I see that used copies are cheap, and available. I recommend grabbing a copy. If the authors are still around to read this review - thanks for a really nice book!
