A nonlinear curve fitting program: Lorentzian, Sine, Power, Exponential series

CurvFit Overview


CurvFit 5.11.5 was downloaded & scanned by our team, against different types of malwares (like viruses, spyware, trojans, backdoors and others) and found CLEAN.

CurvFit (tm) is a curve fitting program for Windows. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked and/or valleys data.

CurvFit is another improved productivity example do to using Calculus (level) programming ... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error, etc.). Helps learn 1) whether math model is good for given data; 2) convergence implies a reasonable solution; 3) how to select new starting initial parameter values. See comments in EX*.? files for ideas on how to converge via solvers.

Interpolation, extrapolation, & Hardcopy Plot options are now available.
