%description
ALGLIB is a cross-platform numerical analysis and data mining library.

ALGLIB features include:
  *  Data analysis (classification/regression, including neural networks)
  *  Optimization and nonlinear solvers
  *  Interpolation and linear/nonlinear least-squares fitting
  *  Linear algebra (direct algorithms, EVD/SVD), direct and iterative
     linear solvers, Fast Fourier Transform and many other algorithms
     (numerical integration, ODEs, statistics, special functions)
