The IMSL Fortran Numerical Library

The IMSL Fortran Numerical Library consists of two separate but coordinated Libraries that allow easy user access. These Libraries are organized as follows:

  • MATH LIBRARY general applied mathematics and special functions

    The User Guide for IMSL MATH LIBRARY has two parts:

    • MATH LIBRARY

    • MATH LIBRARY Special Functions

  • STAT LIBRARY statistics

Most of the routines are available in both single and double precision versions. Many routines for linear solvers and eigensystems are also available for complex and double-complex precision arithmetic. The same user interface is found on the many hardware versions that span the range from personal computer to supercomputer.

This library is the result of a merging of the products: IMSL Fortran Numerical Libraries and IMSL Fortran 90 Library.
