Solaris provides scientific functionalities through its Sun S3L Toolkit^[39] functions. Sun S3L consists of a set of core library functionsthat is, subroutines that perform linear algebra, Fourier transform, and other scientific computationsplus a set of auxiliary utilities, referred to as the toolkit functions.

The GNU Scientific Library (GSL) is a collection of routines for numeric computing. The routines have been written from scratch in C, and they present a modern API for C programmers, allowing wrappers to be written for very high-level languages. The source code is distributed under the GNU General Public License. More information about GSL appears in Chapter 3.
