Gnu Scientific Library 2.0

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License.<br> <br> 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.<br> <br> The complete range of subject areas covered by the library includes, <ul> <li>Complex Numbers</li> <li>Roots of Polynomials</li> <li>Special Functions</li> <li>Vectors and Matrices</li> <li>Permutations</li> <li>Sorting</li> <li>BLAS Support</li> <li>Linear Algebra</li> <li>Eigensystems</li> <li>Fast Fourier Transforms</li> <li>Quadrature</li> <li>Random Numbers</li> <li>Quasi-Random Sequences</li> <li>Random Distributions</li> <li>Statistics</li> <li>Histograms</li> <li>N-Tuples</li> <li>Monte Carlo Integration</li> <li>Simulated Annealing</li> <li>Differential Equations</li> <li>Interpolation</li> <li>Numerical Differentiation</li> <li>Chebyshev Approximation</li> <li>Series Acceleration</li> <li>Discrete Hankel Transforms</li> <li>Root-Finding</li> <li>Minimization</li> <li>Least-Squares Fitting</li> <li>Physical Constants</li> <li>IEEE Floating-Point</li> <li>Discrete Wavelet Transforms</li> <li>Basis splines</li> <li>Running Statistics</li> <li>Sparse Matrices and Linear Algebra</li> </ul> <br> 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.<br>
