GAUSS Systems
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 ofanalysis 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.
Additionally, GAUSS handles
complex numbers automatically and seamlessly. You don't have to keep
track of the real and imaginary parts of a matrix. Complex numbers are
handled automatically, that greatly simplifies programming for
engineering and other tasks that require working with complex numbers.
The Tools You Need
GAUSS has over 400 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
many popular spreadsheets and databases, 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.

GAUSS's high resolution Publication Quality 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 WMF, 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, including most of the latest printers and plotters.© Copyright 2010 Aptech Systems, Inc.
