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.
ODEcalc ODEcalc (tm): An Ordinary Differential Equation (ODE) Calculator! Nonlinear ODEs. State your equation, boundary/initial value conditions it solves your problem. Plots solution y derivative ydot versus x. Calculus Programming demo application.
Match n Freq Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Ys are in freq. A Fortran Calculus demo application.
FC-Win FC-Win (tm) is a front-end program for Fortran Calculus (tm). The Fortran Calculus (FC) language is for math modeling, simulation, and optimization. FC is based on Automatic Differentiation that simplifies computer code to an absolute minimum.
