New Features in GAUSS 4.0

Comprehensive Environment for Modelling and Analysis
GAUSS is a complete analysis environment suitable for performing quick calculations, complex analysis on small or large datasets. The combination of the GAUSS family of products offers an environment that is powerful and versatile enough for virtually any numerical task. The GAUSS System (introduced in 1984) can be described as

  • efficient number cruncher
  • comprehensive matrix programming language
  • an interactive analysis environment

Interactive and Fast
For simple problems GAUSS provides a fully interactive environment for exploring data, creating scenarios and analysing results. For more complex tasks, you can write programs and save them to disk. GAUSS is fast, providing performance comparable to compiled C or FORTRAN programs. And unlike other math packages, GAUSS's speed is equally impressive when working with problems of very large scale.

Easy to use and Efficient
While many GAUSS users never find a need to program extensively, for those who do GAUSS provides a natural and logical environment that is easy to learn and powerful to use. At the core of GAUSS is an efficient programming language adequate for doing sophisticated analysis.

The basic unit of analysis in GAUSS is a matrix, resulting in a syntax closely resembling common mathematical expressions. Since matrix operations are assumed, most of the looping required by other languages is eliminated. Additionally, GAUSS handles complex numbers automatically and seamlessly. This greatly simplifies programming for engineering and other tasks that require working with complex numbers.

The Data Translation Loop allows transformations on variables in a data set by directly using the variable names in expressions. This streamlines data transformations and makes for shorter, more readable programs.

GAUSS's Source Level Debugger greatly simplifies program development. With all of the features you would expect in a dedicated debugging system, you can quickly identify and solve program logic errors at run time

The Tools You Need
GAUSS and GAUSS Applications provide a wealth of mathematical functions built in, including LINPACK and EISPACK routines, factorisations, decompositions, eigenvalues, distributions and equation solving functions, to provide you with the tools you need to solve your problems. You can easily customise or add to the GAUSS function library, and optional modules provide access to many other specialised capabilities. In addition, an entire line of Third Party Applications is available. Written by some of the top experts in their respective fields, these modules offer state-of-the-art analysis solutions.

Other important features include: data import/export compatibility with many popular spreadsheets and databases, built-in functions for efficiently handling sparse data, and a Foreign language Interface for incorporating your favourite compiled C and FORTRAN programs directly in to GAUSS programs.

Visualisation and Presentation
GAUSS's high resolution Publication Quality Graphics gives you powerful ways to visually analyse your data and present your findings. A wide choice of graphing options are available to you, including 2D, 3D, surface, contour, polar and log graphs, as well as bar graphs, histograms, box graphs and more. You can export graphics files in a number of popular formats, including PCX, PIC, and HP-GL/2, as well as Post Script and EPS formats, for use in page layout and presentation packages, and GAUSS includes support for a wide range of output devices, including most of the latest printers and plotters.
