I guess zeros are not included as common elements.
Yes. Seems to be a somewhat "ill-posed" problem...
What does "they share a common row, column entry" mean?
I think it should be a non-zero common row, column entry.
Just consider the problem to be "Is there any i, j such that A(i,j) == B(i,j) == 1"
I guess it means intersection of arrays, literally.
tf=any(ismember([A(:)==1 B(:)==1],[1 1],'rows'));
Re-wording is needed for this problem. Here is how I interpreted the problem:
1. "common row, column entry" means a same value at the same row-column location
2. zeros don't count. You need to check for non-zeros...
