Find nonzero elements in 5x5 matrix (diagonal, vertical, horizontal line)

Hey,

So I'm wondering how to find a string 5 numbers long in a 5x5 matrix.

I'm trying to code a bingo game and my idea is whenever a number [1-100] is called that is also in my "bingo card" (5x5 matix A) to move that value and corrisponding position into another 5x5 matrix (B) of zeros. How can I find when there is a sting 5 numbers (nonzeros, from A) in a diagonal, vertical, or horizontal line.

Any help or advice is much appreaciated.

Thanks,

Ben.

For example, to search for a column string,

A =[

     1     4     4     4     5
     3     1     4     1     4
     5     5     2     2     2
     4     5     4     1     5
     5     4     1     1     1];
     
     
 all(A==[4;1;5;5;4],1)    

ans = 1x5 logical array
   0   1   0   0   0
