How can I check if row matrix B is equal to a row of matrix A?

I have a matrix A = [1 2 3; 4 5 6; 7 8 9]

I randomly generate matrix B = [4 5 6]

How can I check if B is a row of A in ONE loop or using NO loops?

Look Laurie! NO LOOPS!

A = [1 2 3; 4 5 6; 7 8 9];
B = [4 5 6];

[Result,LocResult] = ismember(B,A,'rows')

produces:

Result =

       1

LocResult =

       2

The ‘Result’ output indicates that there is a match, and ‘LocResult’ that the match is the second row.
