Avoid a cycle using lsqcurvefit (or lsqnonlin)

Hi everybody,
I have many curves of experimental data (n*1000) and I need to apply lsqcurvefit function to determine the coefficients of equations. As a result I expect two coefficients to each of my curve. So indeed I can use lsqcurvefit in a cycle to each of my curve. But if there is a way to apply this function without cycle?
Best regards

You would have to do your regressions iteratively in a loop.
I would ask lsqcurvefit for all the outputs, and then store them in a cell array (in a separate assignment line) in the event you find it necessary to calculate confidence intervals on the parameters or the fit, or otherwise compare the individual regressions from a statistical perspective.

Ok. Then is there another way to solve my problem with least-squares methods without a loop? What do you think?

It depends what your problem is.
I have no idea what it is, so I cannot provide a more exact solution.
