Remove duplicated rows in a matrix

Hi

I have some (x,y) points and it consists of some duplicated values, for example (x3,y3) is duplicated 3 times in data. How I can find/remove this point and other duplicated points in all my data?

Thanks.

unique(array,'rows') can do the job:

>> A=[1 2;3 4;5 6;1 2]

A =

       1     2
       3     4
       5     6
       1     2

>> unique(A,'rows')

ans =

       1     2
       3     4
       5     6
