How to use a single value from a multi-variable optimization result?

I used this function to optimize a 5 variable function:

[X, fval] = fmincon(fitnessfcn, x0, [], [], [], [], [0.01,1,300 + 273.15, 8, 10*3.600], [10, 18.3,1200,20,50*3.600], nonlconi);

Now, i want to use results obtained from fmincon in other calculations. How can I do that?

X(1),X(2),X(3),X(4) and X(5) are the optimal values of the solution variables which can be passed to other calculations. What exactly is the problem ?

The X(1),X(2),X(3),X(4) and X(5) obtained here, I need to use them in further calculations, how do i do that?

[Torsten]

By passing their values to the other calculation.

Okay. Thanks.
