Graphing scientific calculator with ample support for user defined functions and libraries. Numeric features include derivation, integration, Monte Carlo simulations, Runge Kutta, matrix inversion, nonlinear equation systems, function minimizer.

DataFitX is a COM component (in-process ActiveX DLL) which allows you to add a powerful nonlinear regression (curve fitting) engine to your software with just a few simple lines of code in any software or development environment that supports COM.

The Fair-Sound provides loudness compensation, an essential element that is conspicuously missing from the WMP9S. Fair-Sound employs a sophisticated system of intelligent filters to compensate for ours ears' nonlinear response at low volumes.

NLREG performs nonlinear regression and curve fitting. NLREG fits a mathematical function whose form you specify to a set of data values. Virtually any type of function can be fitted.

CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions.

Use Visual Fitting to implement linear, nonlinear curve fitting and surface fitting.
