Is it possible to use lsqcurvefit without text messages?

I dont want to see this in the command window:

Local minimum possible.

lsqcurvefit stopped because the final change in the sum of squares relative to its initial value is less than the default value of the function tolerance.

criteria details

x =

498.8309   -0.1013

warning off is not a solution. So what to do?

The following should work:

opt = optimoptions('lsqcurvefit','Display','off');
x = lsqcurvefit(fun,x0,xdata,ydata,lb,ub,opt)

[Mr M.]

what is lb and ub??

[Brendan Hamm]

Lower and Upper bounds on the design variable. Both vectors of the same length as x (or scalars if the bound applies to all elements). If you are not using them simply pass in the empty array in their place:

opt = optimoptions('lsqcurvefit','Display','off');
x = lsqcurvefit(fun,x0,xdata,ydata,[],[],opt)
