I have a 50x3 matrix with numerical values. I want to take all the rows that have 2 zeros or more out For example 0 25 15; 0 0 25; 16 13 12 I only want to get out the first and the third row. And I do not wish to do that manually with 50 rows.

a = [0   25   15;
0   0    25;
16  13   12];
out = a(sum(a == 0,2) < 2,:)
