MATLAB: How to find a vector in a matrix

vector

Hi all, I just wonder whether there are Matlab functions which can deal with the problem. Say,
A=[1 1 1 1; ...
   1 1 2 3; ...
   1 2 3 1; ...
   1 1 1 2];
B=[1 2 3]
So B appears twice in A.
I tried ismember, but it finds all the elements of B in A, regardless of the sequence.
Thanks!

    A=[1 1 1 1; 1 1 2 3; 1 2 3 1; 1 1 1 2];
    B=[1 2 3]; 
    [j,i]=ind2sub(fliplr(size(A)),  strfind(reshape(A.',1,[]),B).' );
    >> [i,j]
    ans =
         2     2
         3     1
