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 C, Java, C#.NET, and Fortran. A Python interface is also available.

The IMSL Libraries were developed by Visual Numerics, which was acquired in 2009 by Rogue Wave Software, which was acquired in 2019 by Minneapolis, Minnesota–based application software developer Perforce.[1]

Version history[edit]

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.
