无标题.bmpThe GAUSS ? Mathematical and Statistical System

The GAUSS Mathematical and Statistical System is a fast matrix programming language widely used by scientists, engineers, statisticians, biometricians, econometricians, and financial analysts.

Gauss数学和统计系统是一个易于使用的基于强有力的Gauss矩阵语言的数据分析系统。它被科学家、工程师、统计学家、生物学家、经济学家和金融分析家用于解决各种问题。
从1984年推广使用以来,Gauss也成为大规模数据处理和复杂建模的标准。世界范围内的接受和政府工业部门及学术领域范围内的使用对它的效能和多功能性给予了有力证明。
Gauss系统能从以下方面给予描述:它是一个非常有效的数据处理者,一种全面的程序设计语言,一个内部相互作用的分析环境。

Designed for computationally intensive tasks, the GAUSS system is ideally suited for the researcher who does not have the time required to develop programs in C or FORTRAN but finds that most statistical or mathematical "packages" are not flexible or powerful enough to perform complicated analysis or to work on large problems.

Whatever mathematical tool or language you are now using, you'll find that GAUSS can greatly increase your productivity!

密集型计算是GAUSS系统的主要任务,它是没有时间学习C或者FORTRAN语言,但是又觉得大多数的统计和数学软件包对于解决复杂的问题不够灵活和强大的研究人员首选的工具。无论你正在使用哪种数学工具或是语言,你会发现GAUSS能够极大地提高效率。

Comprehensive Environment for Modeling and Analysis

建模和分析的综合环境

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.

GAUSS是适合进行快速计算、对数百万数据点进行复杂分析的整合分析平台。无论你是计算分析的新手还是老练的编程人员,GAUSS产品家族为数据可视化提供了一个强大、灵活、容易掌握的平台。从1984年推广使用以来,Gauss也成为大规模数据处理和复杂建模的标准。

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.

世界范围内的接受和政府工业部门及学术领域范围内的使用对它的效能和多功能性给予了有力证明。Gauss系统能从以下方面给予描述:它是一个非常有效的数据处理者,一种全面的程序设计语言,一个内部相互作用的分析环境。GAUSS也许就是你所需要的计算工具。

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.

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 Language

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.

Visualization and Presentation

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.

The Tools You Need

GAUSS has over 400 mathematical functions built in, including LINPACK, 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.

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.

NEW Release: GAUSS 6.0 for Mac OS X

Aptech Systems, Inc., is pleased to announce a new release of GAUSS 6.0 Mathematical and Statistical System to Apple's MacOS X.  This release of GAUSS 6.0 for Mac is compatible with both "Panther" (10.3) and Apple's new operating system "Tiger" (10.4) and now features a native Cocoa GUI.

GAUSS 6.0 for MacOS X provides all of the robust computational features that have

become the hallmark of GAUSS as a powerful and flexible matrix programming language.

GAUSS 6.0 for Mac OS X is available now from Aptech Systems, Inc., or your local dealer.
