|
| //| 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) |
