Function used in Curve Fitting Tool

I wish to know some details regarding the Curve Fitting Tool. I have fitted some data with a custom equation, using the Method 'NonLinearLeastSquares'. Could anybody confirm me that the function used by the Curve Fitting Tool, in this case, is the same than in lsqcurvefit, i.e, lsqnonlin? In this case, the fitting result I have obtained with the Tool would be the same than that provided by using directly lsqcurvefit (with the proper options)? Thank you.
