The MathWorks Announces New Curve Fitting Toolbox for MATLAB; Toolbox Extends MATLAB Functionality for Engineering and Scientific Data Analysis and Modeling

    NATICK, Mass.--July 25, 2001--The MathWorks, Inc., the leading developer and supplier of technical computing software for engineers and scientists, today introduced the Company's newest product for data analysis and modeling, the Curve Fitting Toolbox. For the first time, users have a dedicated tool to perform curve fitting tasks while working within the MATLAB environment. The Curve Fitting Toolbox provides access to routines for preprocessing data, as well as creating, comparing, analyzing and managing models. With these models, users can now quickly understand their data, share information, make decisions, and perform more sophisticated analyses.
    "Feedback from the Beta program indicated the Curve Fitting Toolbox integrates all the important activities needed to perform curve fitting applications," said Mary Ann Branch, development manager at The MathWorks. "Users could immediately see how much time they could save when modeling data in MATLAB."
    The functionality in the Curve Fitting Toolbox is available through an intuitive visual interface and the command line. Key features of the toolbox include:

    --Data pre-processing routines, such as data scaling, sectioning, smoothing, and removal of outliers;
    --A library of standard linear and nonlinear parametric and non-parametric fitting models, including polynomial, exponential, rational, power, peak, Fourier, distribution, and interpolant;
    --Linear and nonlinear fitting methods, from least squares and weighted least squares to robust fitting procedures;
    --Tools for developing custom linear and nonlinear models;
    --Analysis of fits, including interpolation, extrapolation, differentiation, and integration; and
    --Automatic code generation of MATLAB functions directly from the user interface.

    "The Curve Fitting Toolbox is the newest among MathWorks products that support data analysis and modeling. Other toolboxes in this series include Statistics, Optimization, Neural Network, Spline, System Identification, Signal Processing and Wavelet," said Russ Minkwitz, product manager at The MathWorks. "Together, these products offer engineers and scientists a rich set of tools. New user interfaces make it easier for novice and advanced users to get started and put our products to work. In addition, we provide leading-edge algorithms and a flexible development environment to support advanced and application-specific analysis. Educators can also take advantage of these tools for research studies and hands-on teaching, providing students with a solid foundation in advanced data analysis techniques."
    The Curve Fitting Toolbox requires MATLAB 6.1 and starts at $500. The toolbox is currently shipping for Microsoft(R) Windows(R) 95, 98, 2000, NT, Linux, and Unix. Quantity and education discounts are available. Additional information can be found on The MathWorks Web site at www.mathworks.com.
