The IMSL MATH/LIBRARY is a collection of Fortran routines and functions useful in mathematical analysis research and application development. Each routine is designed and documented for use in research activities as well as by technical specialists.

To use any of these routines, you must write a program in Fortran 90 (or possibly some other
language) to call the MATH/LIBRARY routine. Each routine conforms to established conventions in programming and documentation. We give first priority in development to efficient algorithms, clear documentation, and accurate results. The uniform design of the routines makes it easy to use more than one routine in a given application. Also, you will find that the design consistency enables you to apply your experience with one MATH/LIBRARY routine to other IMSL routines that you use.
