Nonlinear Approximation (NLSF-Fit)
Using the new function ApproNonLin, imc FAMOS 7.2 can fit coefficients to given measurement data. Based on real measurement data, up to 8 coefficients of a freely selectable formula are approximated.The approximation is based on the Gauss-Newton algorithm. The calculation is carried out taking into account limits for the coefficients iteratively with a step-width control based on Levenberg-Marquardt.Example: Determination of the decay time of a damped oscillation (see picture).
