I am not certain what result you want.
The unique function might be an option:
A = [30 10
30 191
30 10
45 206
30 191
45 206
45 206
155 206
155 206
170 191
155 206
170 11
170 191
170 11];
[Au,~,ID] = unique(A, 'rows','stable');
Out = [A ID]
Out =
30 10 1
30 191 2
30 10 1
45 206 3
30 191 2
45 206 3
45 206 3
155 206 4
155 206 4
170 191 5
155 206 4
170 11 6
170 191 5
170 11 6
