How to find indices of non duplicate rows in a matrix?

I need to find the indices of non duplicate rows in a matrix and I am not sure if there is a way to do it with:
if for example in the vector case I have:
A = [1 1 2 2 3 4 5 6 6]
I'd like to produce (as these 3 elements are unique in A):
B = [3 4 5]
after somehow building:
unique_indices = [5 6 7]
in this case. The unique function will return a single copy of each element. Is there a quick way to do it? Thanks for tips.
