To shuffle vectors without saving them to a variable first, e.g. to shuffle a for-loop, I recommend adding a function like this to your repertoire:
function v=shuffle(v)
v=v(randperm(length(v)));
end
e.g.
for i=shuffle(1:10)
disp(i)
end

It's indeed an smart solution to use randperm for any vector ar an array.
