How to extract certain rows of a matrix?

Hello all,

I have a matrix having large dimension (165475 X 2). Some of its rows have a coordinate of (0,0). I would like to extract those rows. In other words, I would like each row of my matrix be treated as a vector and I am interested in the index of those rows. Thanks.

Mnr, you could use

 rows = find(all(data==0,2))
