WebThe fminunc solution is not as good as the ga solution. However, fminunc reaches the rather poor solution in relatively few function evaluations. Exit flag 2 means you should take care, the first-order optimality conditions are not met at the reported solution. Use fmincon from Optimization Toolbox. fmincon can sometimes minimize nonsmooth functions. See how … Webexitflag: Integer identifying the reason for termination of the algorithm. output: Structure containing solution information about the optimization. lambda: Structure containing the Lagrange multipliers at the solution with a different field for each constraint type. Only the first output argument is required.
