MATLAB: Comparing two arrays of different length

array

Hi,
I have two arrays like, A=[11 11 2 3; 5 2 6 9] and B=[11 3; 2 9]. I want to know the indices of array A where the column of B is equal to column of A. In this case, the indices are [2 4].
How can I do that?
Thanks in Advance.

You could this to find it:
idx = ismember(A', B', 'rows');
c = 1:size(A, 2);
d = c(idx); % is your answer
