x =
     1     5     9    13    17    21
     2     6    10    14    18    22

>> x(:) = x(randperm(numel(x)))
x =

MATLAB: Finding Duplicate rows

Try this:

AA =sort(A,2);
U = unique(AA,'rows');
R = cell(size(AA,1),1);
for k = 1:size(U,1)
     R{k}=find(ismember(AA ,U(k,:), 'rows'));
end
Rows=R(cell2mat(cellfun(@(x)numel(x)>=2,R,'un',0)));
celldisp(Rows)
