MATLAB: String matrix compare to get common in rows

comparMATLABstring matrix

Deal all, i have a problem to compare two string matrix :
A1 = {'AA', 'b' ; 'cc', 'ff'}
A2 = {'ee', 'AA' ; 'hhh', 'm'}
strcmp(A1,A2)
I get
A1 = 
    'AA'    'b' 
    'cc'    'ff'
A2 = 
    'ee'     'AA'
    'hhh'    'm'
ans =
     0     0
     0     0
But i need to get
'AA' is common between A1 iand A2 in the row 1

>> A1 = {'AA', 'b' ; 'cc', 'ff' ; 'tt', 'kk'; 'XX', 'b'; 'AA', 'b'};
>> A2 = {'ee', 'AA' ; 'hhh', 'm'; 'kk', 'o'; 'ee', 'XX'; 'AA', 'b'};
>> X = cell2mat(cellfun(@ismember,num2cell(A1,2),num2cell(A2,2),'uni',0));
>> [R,~] = find(X);
>> [~,Y] = sort(R);
>> C = [A1(X),num2cell(R)].';
>> fprintf('''%s'' common at row %d\n',C{:,Y})
'AA' common at row 1
'kk' common at row 3
'XX' common at row 4
'AA' common at row 5
'b' common at row 5
