Call SORT with two outputs.

Well, I have found that one of the best ways to learn MATLAB, is just to TRY IT. So make an array and try it. Use simple examples, and just look.

A = round(rand(1,7)*1000)
[As,IDX] = sort(A)

Now what relation do As and IDX have to A? Look at the help for sort if you can't see it.
