A = [0.4049 0.1354 0.0914 0.0578 0.0634 0.0494 0.0494 0.0494 0.0494 0.0494]
B = [1 2 3 4 5 6 7 8 9 10]
So 0.4049 corresponds to 1, 0.1354 corresponds to 2, 0.0914 corresponds to 3 etc. I want A to be sorted in decreasing order and B to be in the order that A has come out in. Sorry I don't know if that is clear.
Thanks in advance.

Try this out:
% sort A in descending order (decreasing A values)
% and keep the sort index in "sortIdx"
[A,sortIdx] = sort(A,'descend');
% sort B using the sorting index
B = B(sortIdx);
Hope this helps.
