Solution for getting only one variable equal to 1 while other two variables 0.

I would like to give input variables as follows: For optimization purpose only one variable is to be given value equal to 1 while other two variables must be given 0. For example, if x(1)=1 then x(2) and x(3) must be equal to 0. Similarly, if x(2)=1, then x(1)=x(3)=0. No two variables should be equal to 1 at a time. Can anybody suggest me 'for loop' or 'if-else loop' for this problem. Thanks in anticipation.

function y=myfitness(x)
y= x(1)+x(2)+x(3);
end

E.g., if I understand your request:

n = 3; % number of elements to use
for k=1:n
    x = zeros(1,n);
    x(k) = 1;
    % You put code here to use x
end
