Hi
I am having some trouble using nlinfit. I keep getting the error:
Warning: The Jacobian at the solution is ill-conditioned, and some
model parameters may not be estimated well (they are not identifiable).
Use caution in making predictions.

as also the error that iterations are maxed out. How is it possible to change the default options so that number of iterations is increased

Thanks
