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
