How lsqcurvefit works?
Lsqcurvefit fits a multi-parameter non-linear function through a single data point using Levenberg-Marquardt algorithm. But for e.g. three parameters I need at least three data points to fit the curve? What is the theory behing this function?
Thank you.

This link describes the algorithms used by lsqcurvefit and the other least squares optimizers
BTW, I believe the trust-region method is the default for LSQCURVEFIT, not Levenberg-Marquardt.
