I think what you meant to do is:

   ind = find(cv(:,z) == 2); % Gives indices of each element in column z which equals 2

And if you're dealing with floating point numbers, instead of integers, be sure to read the FAQ: http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F
