MATLAB: How to remove all rows with the same (specific) elements

MATLABmatricesrow removal

If I have a, say 20×2 matrix, and I want to remove all rows with the entry 0 (column 1), 0 (column 2), how might I do that (and I want to be able to do it without having prior knowledge of the specific locations)?
M=[ 2 2
1 3
5 7
1 2
0 0
1 2
0 0 ]

  • Sean, you could use something like
    M(~any(M,2),:) = [];
