Levenberg Marquardt algorithm (lsqnonlin)

Hi

I want to access the increment value at each step and put some kind of constraint on it. Which variable is used to specify it?

There doesn't seem to be a way of doing that for lsqnonlin. There is an optimization parameter, RelLineSrchBnd, that can be set for mincon, fsolve, lsqcurvefit, and lsqnonlin.
