Hi Asma,
> Now I think it would be wise to get lsqnonlin, lsqcurvefit, nlinfit,
statset, statget, __all_stat_opts__, fmincon and quadprog integratedbefore I begin optimoptions.
I agree with that strategy. Make sure you have documentation, tests and demos for all the new functions you've added. Once they're fully usable, you can go back and work on the options structure if there's time.
