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)

P=[0     8
0    59
4    20
4    47
5    23
5    44
9    20]
[~,i]=unique(P(:,1));
P(i,:)
