CurvFit (tm) is a curve fitting program for Windows 95/98. 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 an example of Fortran Calculus 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. Equation Calculator and Hardcopy Plot prints are now (6/2005) available.
CurvFit is a freeware: there is nothing to pay in order to get and use it. The CurvFit 5.11 free full version contains an installer and an uninstaller, and has a size of 1762 Kilobytes.
