Least squares solvers - Optimization Toolbox
显示 更早的评论
I am working on the least square method using the otimization toolbox.
I would like to know the difference between lsqnonlin solver and lsqcurvefit solver ? I would also appreciate to know the meaning of the output values of: "funccount", "norm of step" and "first order optimality".
Thank you, in advance.

The only difference between the two solvers is the input syntax. lsqcurvefit has the more convenient syntax when the residuals are of the form,
resid = F(theta,x) - y
Explanations for the iterative display headings can be found here:
