MATLAB: Check at least one element is not zero in each row

matrix manipulation

Hello,

The aim is to check in a large matrix A, there is at least one element is not zero in each row. I understand the normal method is

for i = 1: numberOfRow
  % check at least one element is not zero
end

But this is going really slow.

Is there a smart way to verify it?

Thanks in advance.

any(A,2)

Lia = ismember(A,B,'rows')

Anya, you could use

 A = [1 2 3 0 8; 5 0 1 2 2];
 col = find(sum(A==0))
 col =
     2     4

col shows the columns which have at least one zero.
