Numerical Recipes

 "Numerical Recipes" was originally the title of a book that implemented numerical algorithms in different computer languages. They have expanded with a number of books and also offer the algorithms in different electronic forms: both via diskettes and on-line. At this site, they offer information and news on themselves, an on-line store (i.e. you can purchase the routines and books on-line), instructions for their use, free upgrades and bug reports, related information on the Internet, and associated information.
