GAUSS (software)
GAUSS is a matrix programming language for mathematics and statistics, developed and marketed by Aptech Systems. Its primary purpose is the solution of numerical problems in statistics, econometrics, time-series, optimization and 2D- and 3D-visualization. It was first published in 1984 for MS-DOS and is currently also available for Linux, Mac OS X and Windows.
Examples of Functions Included in Run-Time Library
- GAUSS has several Application Modules as well as functions in its Run-Time Library (i.e., functions that come with GAUSS without extra cost)
- Qprog — Quadratic programming
- SqpSolvemt - Sequential quadratic programming
- QNewton - Quasi-Newton unconstrained optimization
- EQsolve - Nonlinear equations solver
GAUSS Applications
A range of toolboxes are available for GAUSS at additional cost. See http://www.aptech.com/products/gauss-applications/ for complete listing of products.
| Algorithmic Derivatives | A program for generating GAUSS procedures for computing algorithmic derivatives. |
| Constrained Maximum Likelihood MT | Solves the general maximum likelihood problem subject to general constraints on the parameters. |
| Constrained Optimization | Solves the nonlinear programming problem subject to general constraints on the parameters. |
