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.
