Best Answer

To begin with, you’re mis-spelling it. From the documentation (for optimoptions):
options = optimoptions(@lsqnonlin,'Algorithm','levenberg-marquardt','MaxFunEvals',1500)
That still may not work, depending on what solver you’re using.
In order to find out what options you have, again from the documentation for optimset:
  • options = optimset(optimfun) creates an options structure options with all option names and default values relevant to the optimization function optimfun.
