How to access the NUMERICAL RECIPES library
The numerical subroutines from the book _Numerical Recipes_ by William Press,
et al. are installed on Project Athena. There are approximately 200 routines,
which cover a large range of subjects. The source code for the routines are
available, and the book documents and explains the mathematics behind the
routines.
Both C and Fortran versions are available in the "recipes" locker. The source
code is in the directory
/mit/recipes/src
To use the libraries from your C program, you'd type:
attach recipes
cc filename `athdir /mit/recipes lib`
To use the libraries from your Fortran program, you'd type:
attach recipes
add -f gnu
g77 -o file file.f -L`athdir /mit/recipes lib` -lrecipes_f
The layout of the recipes locker is as follows:
The src directory has 2 subdirectories, one for C and one for fortran:
src/recipes_c-ansi -----> The Ansi-C version
src/recipes_c-kr -----> The K&R C version
src/recipes_f -----> The fortran version
Each of these subdirectories contain the source for Numerical Recipes and the
source for the demo/example programs. The NR sources are in
src/recipes_{c,f}/recipes
The demo/example sources are in
src/recipes_{c,f}/demo/src
Due to a conflict with libm.a, there were 2 changes made in the Numerical
Recipes "C" sources:
1. erf has been renamed erf_nr
2. erfc has been renamed erfc_nr
