%description
ALGLIB is a cross-platform numerical analysis and data processing 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)
