THE MATHWORKS INTRODUCES STATISTICS TOOLBOX FOR MATLAB; COMBINES INNOVATIVE GUI TOOLS WITH TECHNICAL COMPUTING ENVIRONMENT

 NATICK, Mass., Oct. 18 /PRNewswire/ -- The MathWorks, Inc. today announced the availability of the MATLAB(R) Statistics Toolbox, a suite of statistical techniques for use by engineers and scientists for modeling and data analysis.
 The Statistics Toolbox combines high-level interactive graphic tools and statistical functions with MATLAB's robust mathematical computation and scientific visualization environment. Key supported statistical functionality includes data analysis, probability modeling, and Monte Carlo simulation.
 Interactive "GUI (Graphical User Interface) Tools" for analyzing results are a distinctive feature of the Statistics Toolbox. Instead of using graphics to simply display data as static tables and plots, the MATLAB GUI Tools enable users to interactively change settings and parameter values by clicking and dragging the mouse while simultaneously viewing the changing digital display of the function values at any point.
 The Statistics Toolbox includes MATLAB functions for descriptive, inferential, and graphical statistics and linear models, including:
 -- GUI-based interactive analysis tools
 -- Poisson, normal, binomial, and 11 other probability distributions
 -- Random number generators for Monte Carlo simulation
 -- Box plots, quantile-quantile plots, and normal probability plots
 -- Descriptive statistics to summarize a data sample
 -- Regression, analysis of variance, and polynomial prediction
 -- Interactive contour plotting
 The Statistics Toolbox is open and extensible, enabling users to view and modify algorithms implemented in the toolbox. Users can interactively apply the techniques in the Toolbox or develop new ones in MATLAB's easy-to-use programming environment.
 With MATLAB's language and open architecture, Statistics Toolbox users can rapidly prototype large analytical systems using statistics functions. Using the Toolbox, technical professionals can simulate and quantify the performance of random components in systems and processes, find the best of several alternatives, determine whether a change has occurred and predict the result of a change in a system. These applications are relevant in a number of areas, but are particularly useful in the semiconductor, discrete manufacturing, telecommunications, automotive, food processing, and pharmaceutical industries.
 MATLAB is the most powerful technical computing environment on the market today. It provides numeric computation software, advanced graphics, a high-level programming language, and application-specific toolboxes that allow users to analyze and visualize data, analyze and optimize engineering systems designs and algorithms, and create mathematical models. Specific functionality includes object-oriented graphics, sparse matrix support, sound output, graphical user interface controls and hundreds of other math and graphics operations.
 Pricing for the Statistics Toolbox begins at $295 for single-user microcomputer licenses. Quantity and educational discounts are available.
 The Toolbox, which requires MATLAB 4.0, will ship on all MATLAB 4.0 platforms, including: 386/486 PCs running MS-Windows, Macintosh, Sun SPARC, Hewlett-Packard Series 700, IBM RS/6000, Silicon Graphics, and DEC Ultrix and Alpha/AXP Systems.
 The MathWorks, Inc., based in Natick, Mass., develops, markets and supports high-performance software for interactive numeric computation, visualization, and dynamic system simulation. The MathWorks' products are relied upon by more than 150,000 users at the world's leading commercial and government research laboratories and organizations, and educational institutions.
