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

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"
