PLEASE HELP! Trying to access one variable of a multi-output functiom

This should be an easy fix, but I cant seem to find the answer anywhere. Here's the issue...

I'm trying to use simulannealbnd (a built in matlab function) to evaluate an objective function I have written. The problem is, simulannealbnd can only accept one variable, and my objective function outputs 3 variables into an array. I am only trying to input the third output into the function, but I am unsure how to do this. (I need to use the other outputs of my function in a different part of the code, and so simply deleting them is not an option.)

Here is snippets of my code to show you what I mean:

MOSA_ObjFunc_1.m

function f = MOSA_ObjFunc_1(x)

f(1)=...;
f(2)=...;
f(3)=...;

end

Main.m

% Start with the default options
options = saoptimset;
% Modify options setting
options = saoptimset(options,'MaxIter', MaxIter_Data);

...

options = saoptimset(options,'ReannealInterval', ReannealInterval_Data);

for i=1:2500
[x,fval,exitflag,output] = simulannealbnd(@MOSA_ObjFunc_1,rand(1),lb,ub,options);
%Only need @MOSA_ObjFunc_1 to input f(3) into here
...

Should be an easy fix, but I can't find the answer anywhere!

Thanks in advance.

third = @(x) x(3);
thirdMOSA = @(x) third(MOSA_ObjFunc_1(x));
[x,fval,exitflag,output] = simulannealbnd(thirdMOSA, rand(1), lb, ub, options);

That worked like a charm! Thank you so much!
