Can matlab solve nonlinear problem with nonlinear constraints and 300 variables to decide?
When I try to solve with fmincon following message is released.
Solver stopped prematurely.
fmincon stopped because it exceeded the function evaluation limit,
options.MaxFunctionEvaluations = 3000 (the default value).

Did you just create the options structure or did you pass it into fmincon as part of your call? Merely making the struct does not "change the global settings for fmincon" or anything like that. You have to tell fmincon to use those new options.

Thank you for your help. I added options and updated MaxFunctionEvaluations .
[x,fval] = fmincon(fun,x0,A,b,Aeq,beq,lb,ub,@confuneq,options);

Although increase iteration number and MaxFunctionEvaluations but it shows same message as follows
My guess would be that you created opts, but forgot to feed it to fmincon.
