IMSL® Numerical Libraries for FORTRAN

The IMSL® Libraries contain approximately 900 callable FORTRAN subroutines with applications in engineering, the sciences, and other areas requiring accurate, reliable mathematical computation. The libraries allow problem solvers to save time and money in application program development by letting users select complete, tested Fortran subprograms instead of writing them. The MATH/Library contains subprograms for numerous mathematical capabilities including matrix operations, linear systems, integration, transforms, and others. It includes special functions including trigonometric functions, exponential integrals, and many others. The STAT/Library provides subprograms for regression analysis and other specialized statistical functions.
