How to fit a 2D Gaussian function to noisy data in Matlab? Or data with another number of dimensions and arbitrary fit function?It took me a while to find out how Matlab does this by the functions lsqcurvefit, fmincon or fminsearch. This project demonstrates how to use these functions to fit ND...

PDL::Fit::LM is a Levenber-Marquardt fitting routine for PDL. Currently, only Levenberg-Marquardt fitting is implemented. Other procedures should be added as required. For a fairly concise overview on fitting see Numerical Recipes, chapter 15 "Modeling of data". SYNOPSIS use PDL::Fit::LM;...

PDL::Fit::Levmar is a Perl module with Levenberg-Marquardt fit/optimization routines. Levenberg-Marquardt routines for least-squares fit to functions non-linear in fit parameters. This module provides a PDL ( PDL::PDL ) interface to the non-linear fitting library levmar (written in C). Levmar...

Baseline Fit each column in "x".There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput.Syntax: [ycorr,yfit] = bf(y,pts,avgpts,method,confirm); ycorr = bf(y); ycorr = bf(y,method); A baseline fit is interpolated...
