d = [a/2-1,a/2-];

However if you wish to use a for-loop and the if-else construct, it would be something like this:

for k = 1:size(a,1)
if a(k) == 2
d(k,:) = [0,0];
else
d(k,:) = [1,1];
end
end

I would advise you to read the pertinent documentation on this carefully.  The for-loop index should not be altered as you have done with "i=i+1" since that is automatically done.  Also "b(i)=2" is not correct.  Use "==" for equality tests.
