IMSL Numerical Libraries

IMSL (International Mathematics and Statistics Library) is a commercial collection of software libraries of numerical analysis functionality that are implemented in the computer programming languages of C, Java, C#.NET, and Fortran. A Python interface is also available.

The IMSL Libraries are provided by Rogue Wave Software.

The first IMSL Library for the Fortran language was released in 1970, followed by a C language version originally called C/Base in 1991, a Java language version in 2002 and the C# language version in 2004.

Several recent product releases have involved making IMSL Library functions available from Python. These releases are Python wrappers to IMSL C Library functions (PyIMSL wrappers) and PyIMSL Studio, a prototyping and production application development environment based on Python and the IMSL C Library. The PyIMSL wrappers were first released in August 2008. PyIMSL Studio was introduced in February 2009. PyIMSL Studio is available for download at no charge for non-commercial use or for commercial evaluation.
