which, I presume you recognize can be created as
xy=sort([x y]);
?

No klew. What does cX have to do w/ any of the above other than it is the same length? I see no correlation of locations of the 1's in cX to the values of x,y or xy.
If you're looking at logical, then
iX = logical([1 0 1 0 1 0 1 1 0]); iY = ~iX;
but how to set the particular locations is needing the crystal ball...
