Comprehensive Environment for Modeling and Analysis
GAUSS is a complete analysis environment suitable for performing quick
calculations, complex analysis of millions of data points, or anything in
between. Whether you are new to computerized analysis or a seasoned programmer,
the GAUSS family of products combine to offer you an easy to learn environment
that is powerful and versatile enough for virtually any numerical task. Since
its introduction in 1984, GAUSS has been a standard for serious number crunching
and complex modeling of large-scale data.
Worldwide acceptance and use in government, industry and the academic community
is a firm testament to its power and versatility. The GAUSS System can be
described several ways: It is an exceptionally efficient number cruncher, a
comprehensive programming language, and an interactive analysis environment.
GAUSS may be the only numerical tool you will ever need.
Interactive and Fast
For simple problems GAUSS provides a fully interactive environment for exploring
data, creating scenarios and analyzing results. For more complex tasks, you can
write programs and save them to disk. GAUSS is exceptionally 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.
Straightforward 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 even the most 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. 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.

As a complete programming language, the GAUSS system is both flexible and
powerful. Immediately available to the GAUSS user is a wide variety of
statistical, mathematical and matrix handling routines. GAUSS can be used either
interactively for short one-off commands or by creating large programs
consisting of several files and libraries of functions, or anything in between.
ViVisualization and Presentation
GAUSS's high resolution graphics gives you powerful ways to visually analyze
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. Graphs can be placed in
individual overlapping or tiled windows on a single page. You can export
graphics files in a number of popular formats, including JPEG, SVG, PNG,
HP-GL/2, PostScript and EPS formats, for use in page layout and presentation
packages, and GAUSS includes support for a wide range of output devices.
The Tools You Need
GAUSS has over 400 highly-optimized mathematical functions built in, including
LAPACK, EISPACK and BLAS routines, factorizations, decompositions, eigenvalues,
distributions and equation solving functions, to provide you with all the tools
you need to solve your most difficult problems. You can easily customize or add
to the GAUSS function library, and optional modules provide access to many other
specialized capabilities.
The GAUSS Run-Time Module (GRTM) allows users to distribute GAUSS applications
that they have written to people who do not have GAUSS. Developers distribute a
compiled file to end users along with the GRTM. This is available with GAUSS at
no extra charge.
Other important features include: data import/export compatibility with
spreadsheets, long period random number generators, built-in functions for
efficiently handling sparse data, and a Foreign Language Interface for
incorporating your favorite compiled C and FORTRAN programs directly into GAUSS
programs.p>
