Non linear least square function lsqnonlin

I was wondering if there is a way to stop the lsqnonlin function before converge to the optimal solution.

You can apply your own stopping criterion in any of the Optimization Toolbox solvers using the OutputFcn option, e.g.,

options = optimoptions(@lsqnonlin,'OutputFcn',@myFunction)

Similarly, you could limit the number of iterations to some desired maximum if that's what you're trying to do.

options = optimoptions(@lsqnonlin,'MaxIter',Nmax)
