Confidence index of lsqcurvefit?

Hi,
I am using the lsqcurvefit function in a model, and am wondering what the default confidence index is for the coefficients that the lsqcurvefit spits out. ( x = lsqcurvefit(@myFun,x0,x,y,lb,ub,options) I have looked through the options and cannot seem to find something that will give me a confidence index of the coefficients.
Thank you in advance for any help

The output of 'lsqcurvefit' will not give you confidence limits on the estimated parameters. You have to use 'nlparci' to calculate them. (It defaults to 95% confidence limits, but you can change those.) You can also use 'nlpredci' to get confidence intervals on the fitted curve.
