- Brian's Programs
- ________________
-
-
- This directory contains various programs, functions and
- procedures which I have found useful in performing various
- calculations. Some are based on code found in Numerical Recipes
- by Press, et. al. and some have originated from the remarkable
- approximation algorithms of C. Hastings, found either in his book
- Approximations for Digital Computers or in the Handbook of
- Mathematical Functions by Abramowitz and Stegun.
-
- Some of the other programs I have written myself, and they
- quite likely need improving! In particular the program "Plot"
- was developed out of an earlier, rather different, program. This
- would benefit from rewriting and making it run in a Risc-Os
- window using colours etc.
-
- Anyway, I hope you will find this a useful collection of
- routines.
