avoiding same data in looping

Hii... I am a very new MATLAB user, I want to ask how to avoid same data when I do random looping, Example, I have A = [ x y z], I want to do looping, but every value does not have same value, ex: if I have data from 1 to 3, if x=1, y and z should not be 1 (should be 2 or 3). How to make the m-file?

Thank You

For A=1:3
fprintf('The value of A is: %d\n',A);
end

Thank you.. how if A = [1 3 2] or A = [2 1 3], like randomly chosen data, actually I want to do cross-validation? thank you..

For that, you can use randperm(N), e.g. A=randperm(3)
