-A cross-platform numerical analysis and data processing library. It supports
-several programming languages (C++, C#, Pascal, VBA) and several operating
-systems. 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)
-
-This is a free edition of alglib.
