+      ALGLIB is a cross-platform numerical analysis and data processing library. It supports several programming languages (C++, C#, Delphi) and several operating systems (Windows and POSIX, including Linux). ALGLIB features include:
+
+      * Data analysis (classification/regression, statistics)
+      * 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
