The NSWC Mathematics Subroutine Library is a collection of Fortran 77 routines specializing in numerical mathematics collected and developed by the U.S. Naval Surface Warfare Center.
This software is made available, without cost, to the general scientific community. The 1993 edition is an update of the 1990 edition. NSWC has made every effort to include only reliable, transportable, reasonably efficient and easy to use code in this library. They have thoroughly tested all the routines on a variety of machines ranging from supercomputers to PC's.
