Random start on esfit with command line
Posted: Mon Jun 18, 2018 1:41 am
Hi, I have a problem of Random Start on esfit without GUI.
I used EasySpin 5.2.16 on MATLAB 2016a on Widows 10 x64.
As described in the manual, FitOpt.RandomStart = 0 should mean the fitting starts with a center value.
But esfit does not accept FitOpt.RandomStart = 0, it always starts with random values.
If I did not set FitOpt.RandomStart field, esfit started with a center value.
If the field RandomStart in FitOpt structure, esfit starts with random values independent on the value of FitOpt.RandomStart.
For example, the following settings always gives me a random start in the esfit calculation.
Is that a bug?

Code: Select all
SimOpt = [];
FitOpt.Method = 'levmar fcn';
FitOpt.Scaling = 'lsq0';
FitOpt.RandomStart = 0;
FitOpt.PrintLevel = 1;
FitOpt.TolFun = 1e-6;
FitOpt.lambda = 1e-3;
FitOpt.delta = 1e-6;
BestSys = esfit('chili',Spc_exp,Sys,Vary,Exp,SimOpt,FitOpt);
