The functions from the Optimization Toolbox check the latter threshold by means of property 'MaxTime' only after the cost function evaluation has been finished. This means, that the functions from the Optimization Toolbox do not take the computational time needed for the custom cost function into consideration when checking the defined threshold 'MaxTime'. In other words, the computational time for the optimization iterations might be affected by the computational time needed by the custom cost function and this cannot be constrained by means of property 'MaxTime'.
In this case one needs to manually check if the computation of the cost function may exceed the desirable limit and stop it with a default value accordingly.
