The IMSL C Numerical Libraries provide advanced mathematical and statistical functionality for programmers to embed in their existing or new applications. Written in standard C, the IMSL C Numerical Libraries can be embedded into any C or C++ application, as well as any existing application that can reference a C library.

The IMSL C Numerical Libraries are supported across a wide range of hardware and operating system environments including Windows, Linux and many UNIX platforms. The user interface for the functions in the libraries is consistent across these platforms.

This guide provides the supporting documentation for the functions in the IMSL C Math Library component of the IMSL C Numerical Libraries, including the API, a usage description, and examples for each function.
