The GNU Scientific Library (GSL) is a collection of routines for
numerical computing. The routines are written from scratch by the GSL
team in ANSI C and present an Applications Programming Interface
(API) for C programmers, while allowing wrappers to be written for very
high level languages.

numerical computing. The routines are written from scratch by the GSL
team in ANSI C and present an Applications Programming Interface
(API) for C programmers, while allowing wrappers to be written for very
high level languages.

The library covers the following areas:

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
