• BLAS (Basic Linear Algebra Subprogram) support;
• Chebyshev Approximation;
• Complex numbers;
• Differential Equations;
• Discrete Hankel Transforms;
• Discrete Wavelet Transforms;
• Eigenvalues and Eigenvectors;
• Fast Fourier Transforms;
• Histograms;
• IEEE Floating Point Calculations;
• Interpolation;
• Least Squares Fitting;
• Linear Algebra;
• Minimization;
• Monte Carlo Integration;
• N-Tuples;
• Numerical Differentiation;
• Permutations;
• Physical Constants;
• Quadrature (Numerical Integration);
• Quasi-Random sequences;
• Random Distributions;
• Random Numbers;
• Root finding of general nonlinear equations;
• Roots of Polynomials;
• Running Statistics;
• Series Acceleration;
• Simulated Annealing;
• Sorting;
• Sparse Matrices and Linear Algebra;
• Special Functions;
• Statistics;
• Vectors and matrices;

Usage:

gcc myprog.c -lgsl -lgslcblas

compiles myprog.c and links it with GSL and the necessary BLAS routines.
