finding overlapping and non-overlapping values in matrix

I have

A = [3    16     4    16
     3    21     4    21
     3    29     3    29
    17    27    18    29
    25    72    26    72
    61    70    61    70
    62    63    62    63];

A(1,;) has overlap with A(2,:) and A(3,:) 
A(2,:) has overlap with A(1,:) and A(3,:) 
A(3,:) has overlap with A(1,:), A(3,:) and A(4,:) 
A(4,:) has overlap with A(3,:)
A(5,:), A(6,:) and A(7,:) ---> do not have any intersection to others

result should be

overlapping_rows = [3    16     4    16
                    3    21     4    21
                    3    29     3    29
                   17    27    18    29]
          
non_overlapping_rows = [25    72    26    72
                        61    70    61    70
                        62    63    62    63]

Try the following code:

A=[3 16 4 16;3 21 4 21;3 29 3 29;17 27 18 29;25 72 26 72;61 70 61 70;62 63 62 63];
Un=0;
for i=1:size(A,1)
   idx{i}=setdiff(find(any(ismember(A,A(i,:)),2)),i);
   if i>1
       Un=union((idx{i}),Un);
   end
end
Un=setdiff(Un,0);
overlapping_rows=A(Un,:)
non_overlapping_rows=A(setdiff(1:size(A,1),Un),:)
