Hi, Suppose if i get the array like this
m=
1 14 56
2 12 45
2 34 65
3 78 56
4 64 34
4 45 23
.......
but i want to delete rows having same ids{but different coordinates},
here-'2',and -'4' . i.e want to retain any one of the rows '2' and '4'.
somewhat like this..
m=
1 14 56
2 12 45
3 78 56
4 64 34
.......
It could be any id, [not only 2 and 4].
