I wrote a custom function that outputs a vector of residuals from experimental - simulated for a dozen or so spectra. I'm trying to use esfit to minimize this vector from my function, but keep getting an error.
Specifically:

Error using ~=
Too many input arguments.

Error in /home/derek/Documents/MATLAB/easyspin/easyspin/esfit.p>esfit (line 130)

Output from function is [x,y] = myfunction(Sys,Exps,Opt)
Providing esfit('myfunction',thegoal,Sys,Vary,Exps,Opt) where 'thegoal' is a vector of zeros of equal length and dimensions as y.

Any help with what is causing the error at line 130 of esfit would be greatly appreciated. I can attach a test data set, script, and the function if helpful.

Are you using an array of experiments structures? The line in esfit that causes the error is If you use an array of structures in Exp, this will give the error you observe.

You are correct.

So the correct way to do this is to make the parameter(s) I want to vary an array instead of having an array of structures, i.e. do Exp.Field = [350, 351, 352, 353...]. Then per iteration of my custom function create a structure input that salt will be happy with, i.e. NewExp.Field = Exp.Field(i)?

EDIT: So implementing that got me one line further.

Error using esfit (line 131)
Exp.nPoints is 1024, but the spectral data vector is 1 long.

I think I know what to do from here, though. Will post a reply if I get stuck again. Thank you for the help!
