- DataFit
DataFit is a tool for performing curve fitting, statistical analysis & data plotting. Fit equations with up to 100 parameters to data with up to 20 independent variables. Define your own equations or choose from over 600 pre-defined equations.
- SimplexNumerica
2D/3D technical graphics plotting and data analysis software for your plotting needs. Curve fitting, FFT and a presentation software! Download a demo of our analysis and plotting software!
- NLREG
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.
- CurvFit
a curve fitting program: Lorentzian, Sine, Exponential and Power series are available models to match your data. A
Lorentzian series is recommended for real data especially for multiple peaked data.
