options = optimset('​MaxFunEval​s',999) does not work

Hi all,

I've also tried

hybridopts = optimset('MaxFunEvals', 1200)

And keep on getting:

lsqcurvefit stopped because it exceeded the function evaluation limit, options.MaxFunEvals = 200 (the default value).

Running Matlab 2012a on linux 64bit, using lsqcurvefit with std-options.

Any help?

thx...

Are you sure you are using your 'hybridopts' when you call lsqcurvefit? Because you say that you are using it with 'std-options'.

[Friedrich]

do you pass down those options to the actual lsqcurvefit call?

[oxy]

what do you mean by "pass"?

You have to include the options in the function call. Something like

 x = lsqcurvefit(fun,x0,xdata,ydata,lb,ub,hybridopts)
