I was optimizing a function named ML with fmincon to find the parameter "theta",
twostage = fmincon(@(theta)ML(theta,param,x,y),theta,[],[],[],[],lb,ub,[],options);
now I want to optimize another function ML2 for two parameters "theta1" and "theta2", can fmincon optimize a function for 2 parameters? how should I write the function?
Thanks

Make theta a 2x1 vector instead and rewrite ML accordingly, to interpret theta as a 2x1 input vector. Also make ub and lb 2x1.

thanks so you mean I should use theta(1) and theta(2) instead of theta1 and theta2 in ML function

Yes, although once theta has been passed to ML, there's no reason you couldn't unpack as follows within the ML code:
theta1=theta(1);
theta2=theta(2);
