Find row in matrix.

Hi, everyone. There are some data in array:

 A=[3 3 2011;22 3 2011;23 3 2011;24 3 2011;25 3 2011;26 3 2011;27 3 2011];

I'm trying to find matching data using 'ismember':

 B=[23 3 2011;27 3 2011];
 [tf, index]=ismember(A,B);

But A(1,1) is also written as correct value. How can I solve it?

Ok, and if we have:

 A=[3 3 2011 3 6;
   22 3 2011 7 3;
   23 3 2011 6 4;
   24 3 2011 1 3;
   25 3 2011 5 4;
   26 3 2011 9 7;
   27 3 2011 3 2];

Then simply do

[tf, index]=ismember(A(:,1:3),B,'rows');

BTW you may want to update your problem next time instead of adding an answer to rephrase the question.
