I have few points (0,8),(0,64),(28,1)(28,66),(9,47)(9,20),(54,20)(54,47),(21,10),(21,51)
Is there any matlab command which checks the x coordinate and select only unique point (based on x coordinate)
e.g (0,8),(28,66)(9,47),(54,20),(21,10)

code is
points = [];
for i = 1:length(right_side)
I = find(left_side == right_side(i));
for j=1:length(I)
points = [points;a(i),a(I(j))];
end
end
points
