It is free software under the GNU General Public License. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite. The complete range of subject areas covered by the library includes, Complex Numbers Roots of Polynomials Special Functions Vectors and Matrices Permutations Sorting BLAS Support Linear Algebra Eigensystems Fast Fourier Transforms Quadrature Random Numbers Quasi-Random Sequences Random Distributions Statistics Histograms N-Tuples Monte Carlo Integration Simulated Annealing Differential Equations Interpolation Numerical Differentiation Chebyshev Approximation Series Acceleration Discrete Hankel Transforms Root-Finding Minimization Least-Squares Fitting Physical Constants IEEE Floating-Point Discrete Wavelet Transforms Basis splines Unlike the licenses of proprietary numerical libraries the license of GSL does not restrict scientific cooperation. It allows you to share your programs freely with others. Downloading GSL The current version is GSL-1.11. It was released on 31 March 2008. Details of recent changes can be found in the NEWS file. This is a stable release. GSL can be found in the subdirectory /gnu/gsl/ on your favorite GNU mirror. Main GNU ftp site: ftp://ftp.gnu.org/gnu/gsl/ For other ways to obtain GSL, please read How to get GNU Software Installation instructions can be found in the included README and INSTALL files. Precompiled binary packages are included in most GNU/Linux distributions. A compiled version of GSL is available as part of Cygwin on Windows (but we recommend using GSL on a free operating system, such as GNU/Linux). Documentation GSL includes a 500 page reference manual in Texinfo format. You can print the manual in postscript or read it on your system using the shell command info gsl-ref (if the library is installed). The GSL Reference Manual is available online, GSL Reference Manual - HTML GSL Reference Manual - Gzipped Postscript GSL Reference Manual - Japanese Translation (by Daisuke Tominaga, AIST Computational Biology Research Center) The manual has been published as a printed book (under the GNU Free Documentation License), GNU Scientific Library Reference Manual - Revised Second Edition, M. Galassi et al, ISBN 0954161734 (paperback) RRP $39.99. All the money raised from the sales of the manual helps to support the development of GSL --- see www.network-theory.co.uk for ordering information. Supported Platforms GSL is developed on the following platform, GNU/Linux with gcc It has been reported to compile on the following other platforms, SunOS 4.1.3 & Solaris 2.x (Sparc) Alpha GNU/Linux, gcc HP-UX 9/10/11, PA-RISC, gcc/cc IRIX 6.5, gcc m68k NeXTSTEP, gcc Compaq Alpha Tru64 Unix, gcc FreeBSD, OpenBSD & NetBSD, gcc Cygwin Apple Darwin 5.4 Hitachi SR8000 Super Technical Server, cc We require that GSL should build on any UNIX-like system with an ANSI C compiler, so if doesn't, that's a bug and we would love a patch! If you have found a bug, please report it to bug-gsl@gnu.org. Previously submitted bug reports can be found in the bug-gsl mailing list archives and the GSL bug database. Mailing Lists Follow the links to the individual mailing lists below to subscribe or view the list archives: Bug-gsl <bug-gsl@gnu.org> mailing list -- bug reports for the GNU Scientific Library should be sent here Help-gsl <help-gsl@gnu.org> users mailing list -- for questions about installation, how GSL works and how it is used, or general questions concerning GSL. Info-gsl <info-gsl@gnu.org> mailing list -- announcements of new releases are made here. Gsl-cvs <gsl-cvs@gnu.org> mailing list -- automated notifications of commits to the repository. Motivation Here are some of the main benefits of using a free scientific library under the GNU General Public License, allows easier collaboration, library is freely available to everyone. software using the library can be released publicly as source-code. you can adapt the source code to your needs. respects your privacy - does not impose any conditions on "in-house" use. you can contribute back improvements to the user community. Special Features The library uses an object-oriented design. Different algorithms can be plugged-in easily or changed at run-time without recompiling the program. It is intended for ordinary scientific users. Anyone who knows some C programming will be able to start using the library straight-away. The interface was designed to be simple to link into very high-level languages, such as GNU Guile or Python The library is thread-safe. Where possible the routines have been based on reliable public-domain Fortran packages such as FFTPACK and QUADPACK, which the developers of GSL have reimplemented in C with modern coding conventions. The library is easy to compile and does not have any dependencies on other packages. Licensing GSL is distributed under the terms of the GNU General Public License (GPL). The reasons why the GNU Project uses the GPL are described in the following articles: Copyleft: Pragmatic Idealism by Richard Stallman Why you should not use the Lesser GPL for your next library by Richard Stallman Additional information for researchers is available in the following article: Releasing Free Software if you work at a University by Richard Stallman Some answers to common questions about the license: If I write an application which uses GSL, am I forced to distribute that application? No. The license gives you the option to distribute your application if you want to. You do not have to exercise this option in the license. If I wanted to distribute an application which uses GSL, what license would I need to use? The GNU General Public License (GPL). The bottom line for commercial users: GSL can be used internally ("in-house") without restriction, but only redistributed in other software that is under the GNU GPL. More Information If you would like to refer to the GNU Scientific Library in a journal article, the recommended way is to cite the reference manual, e.g. M. Galassi et al, GNU Scientific Library Reference Manual (2nd Ed.), ISBN 0954161734. If you want to give a url, use "http://www.gnu.org/software/gsl/". Purchasing printed copies of the GSL manual or GSL support from Network Theory Ltd helps fund the development of the library. These are provided by Brian Gough, one of the developers of GSL. Related Packages GSL requires a BLAS library for vector and matrix operations. The default CBLAS library supplied with GSL can be replaced by the tuned ATLAS library for better performance, ATLAS - a portable self-optimising BLAS library with CBLAS interface ATLAS is free software and its license is compatible with the GNU GPL. Other packages that are useful for scientific computing are: GLPK - GNU Linear Programming Kit FFTW - Large-scale Fast Fourier Transforms Both of these packages are free software (GNU GPL). Development As of 2008, GSL development is hosted on Savannah.gnu.org athttp://savannah.gnu.org/projects/gsl The repository is available via 'git' withgit clone git://git.savannah.gnu.org/gsl.git Read-only CVS access is available withcvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/gsl.git checkout -d gsl HEAD Note: if you use GIT or CVS, you will need automake, autoconf, libtool, GNU m4, GNU make, and GNU Texinfo (makeinfo). To begin the build process from a CVS checkout, start with:$ ./autogen.sh which will prepare the package for compilation. You can then use ./configure --enable-maintainer-mode and make in the usual way. Commit notifications are sent to the gsl-cvs mailing list. In addition to the GSL Reference Manual, anyone wanting to work on the library should read the GSL design document, GSL Design Document - HTML GSL is a mature library with a stable API. The main emphasis is on ensuring the stability of the existing functions, tidying up and fixing any bugs that are reported. Potential contributors are encouraged to gain familiarity with the library by investigating and fixing known problems in the BUGS database. To maintain stability, any new functionality is encouraged as packages, built on top of GSL and maintained independently by their authors, as in other free software projects. The design of GSL permits extensions to be used alongside the existing library easily by simple linking. Discussions about the development of the library take place on the gsl-discuss@sourceware.org mailing list. Any comments from experts in numerical analysis are welcome. GSL is part of the GNU Project and so follows the GNU Coding Standards. Extensions/Applications The following third-party packages provide extensions to GSL. If you want to add a feature to GSL we recommend that you make it an extension first. We will list it here so that people can try it out.

The example programs in the book use the GNU Scientific Library and are free software (the source code is included on a CDROM with the book). Further information about this book is available from the publisher at Springer.de. Project Background The project was conceived in 1996 by Dr M. Galassi and Dr J. Theiler of Los Alamos National Laboratory. They were joined by other physicists who also felt that the licenses of existing libraries were hindering scientific cooperation. Most of the library has been written by a relatively small number of people with backgrounds in computational physics in order to provide a consistent and reasonably-designed framework. Overall development of the library and the design and implementation of the major modules was carried out by Dr G. Jungman and Dr B. Gough. Modules were also written by Dr J. Davies, R. Priedhorsky, Dr M. Booth, and Dr F. Rossi, along with many useful contributions from others in the user community. Debian packages for the library are maintained by Dr D. Eddelbuettel.
