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 available for Linux, macOS and Windows.{{cite web|url=https://www.aptech.com/resources/tutorials/beginner-program-nearest-neighbor-search/#step-1-create-a-new-gauss-program-file|title=Beginner Program: Nearest Neighbour Search|website=Aptech|access-date=2020-02-06|quote=GAUSS does not require any particular file extension for GAUSS program files, however, {{mono|.gss}} is recommended.}}
Examples
- 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.{{Cite web |title=Explore GAUSS Application Modules {{!}} Aptech |url=https://store.aptech.com/gauss-applications-category.html |access-date=2022-03-29 |website=store.aptech.com}}
