You could use something like this for your outer loop of making variable selections:
patterns = dec2bin(0:7);
for k=1:8
usevariable = patterns(k,:)-'0';
% usevariable (1), usevariable (2), usevariable (3) are either 0 or 1
% you can then pick to use x1, x2, x3 depending on associated value of usevariable
% the pattern will cover all posibilities in the loop
end
