Given two matrices filled with ones and zeros, determine if they share a common row, column entry. These matrices are of identical size.
Examples:
Inputs A = [1 0 0 0 0
0 1 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1 ]
and B = [0 1 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1
1 0 0 0 0 ]
Output tf is false
Inputs A = [1 1 1 0 1
1 1 1 1 0
0 1 1 1 1
1 0 1 1 1
1 1 0 1 1 ]
and B = [0 1 0 0 0
1 0 0 0 0
0 0 0 0 1
0 0 0 1 0
0 0 1 0 0]
Output tf is true

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.
Do you mind do explain in a different way? it is not clear for what exactly i should do. It miss 3 problems for me, but in any of them it is not clear the problem itself.
A small addendum to the comment of Chien-Han Su
Just consider the problem to be "Is there any i, j such that A(i,j) == B(i,j) and A(i,j) or B(i,j) ~=0"
Problem description is poor.
Please explain this problem for further clarity
