How to access the Numerical Recipes library
Context
The numerical subroutines from the book "Numerical Recipes" by William Press, et al. are installed on 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.
Steps
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:
- erf has been renamed erf_nr
- erfc has been renamed erfc_nr
