how can I link 4 vectors based on their length? that is from the longest to the shortest

I.e.

I have a=[5 5 5 5 5], b=[4 4 4 4], c=[3 3 3] and d=[2 2].

I want to concatenate out=[a b c d] without knowing, however, the length of a, b, c, d in each cycle.

Thank you.

values = {a, b, c, d};
lens = cellfun(@length, values);
[~, idx] = sort(lens, 'descend');
out = [values{idx}];
