Optimization problem multivariable using fmincon

I'm trying to use fmincon to optimize a certain function of 515 parameters between 0 and 1, the calculationtime for a single set of parameters is 12 seconds. Now if I try to use Fmincon it seems to take forever.

options=optimoptions('fmincon','MaxFunctionEvaluations',2,'MaxIterations',1);

fmincon(@allocatie_optimalisatie_function,parameters,[],[],[],[],lb,ub,[],options)

I would assume that with these settings is should only take a maximum of 24 seconds.

Thank you in advance

Yes, it should be near 24 seconds? Are you getting any unexpected results?
