Uncertainty of fit
Hi all, I am trying to get uncertainties of best fit parameters from fminsearch function. It will be easy if I have a normal Matlab script as fit function, but I use Matlab to call a Linux program to calculate signal from input parameters. So, I created a Matlab function with some input parameters, the output is calcu... 8 Apr 2010 15:10
