What does A have to do with your question? A is not a matrix, and it does not contain only ones and zeros, so it is unclear how it relates to your question.

>> M = randi(0:1,5,6)
M =
0 1 1 1 0 1
0 1 0 0 0 1
1 0 0 0 1 0
1 1 1 0 0 1
0 0 0 1 1 1
>> sum(cumsum(M,1) & M==0, 1)
ans =
1 2 3 3 1 1

@ntsh kr: read the MATLAB documentation. It is easy to search using any internet search engine. This was the first result returned when I searched for "MATLAB cumsum":
