|
//| Implementation of ALGLIB library in MetaQuotes Language 5 |
|
|
//| |
|
|
//| The features of the library include: |
|
|
//| - Linear algebra (direct algorithms, EVD, SVD) |
|
|
//| - Solving systems of linear and non-linear equations |
|
|
//| - Interpolation |
|
|
//| - Optimization |
|
|
//| - FFT (Fast Fourier Transform) |
|
|
//| - Numerical integration |
|
|
//| - Linear and nonlinear least-squares fitting |
|
|
//| - Ordinary differential equations |
|
|
//| - Computation of special functions |
|
|
//| - Descriptive statistics and hypothesis testing |
|
|
//| - Data analysis - classification, regression |
|
|
//| - Implementing linear algebra algorithms, interpolation, etc. |
|
|
//| in high-precision arithmetic (using MPFR) |
