perhaps you should specify that y is in the order of the first occurence of each unique element of x
This would be a better problem if unique and sort functions were not allowed
Solution without using sort(.) or unique(.) .
Solution without using sort(_) or unique(_) .
Note 1) this solution does not use sort() anywhere :) 2) the more elegant "stable" is not available for unique in pre-2012 MATLAB.
