MATLAB: Option for fmincon is not working

fminconmatlab functionoptimization

I defined the option as follows and it is not working. I tried many other options as well. Could anyone gives some idea ? Thanks 
options = optimoptions('fmincon','Algorithm','interior-point','Display','iter-detailed',...
    'MaxFunctionEvaluation',100000,'MaxIterations',2000,'FunctionTolerance',1e-10);
A=[]; b =[]; Aeq =[]; beq =[]; %x is vector  
[V,fval,exitflag,output,lambda,grad,hessian] = fmincon(fun,x,A,b,Aeq,beq,LB,UB,options)

I got it why. The nonlcon argument has been skipped.
[V,fval,exitflag,output,lambda,grad,hessian] = fmincon(fun,x,[],[],[],[],LB,UB, [],options);
Thanks
