identify similarly repeated rows

Good day everyone,

Would like some assistance in finding repeated rows in the following matrices:

A = [ 27 89;
         76 44;
         10 3;
         11 99;
          5 6]

B = [ 11 19;
         76 44;
         16 72;
         11 99;
         54 61;
         65 11]

C = [ 27 89;
         10 3;
         11 99;
          5 6;
          32 12;
         109 56
          76 44 ]

How can I achieve the output as follows: ?

output = [ 76 44;
                11 99]

These are the output since '76,44' and '11,99' are repeated in all the matrices.

take care
ben

Use two 'intersect' calls with the 'rows' option.
