Hi, Sir how can i find the sorted indexing of the array when i am sorting it in the same code??

A =  [2 9 6 5 8]
swapped = 1;
while swapped
  swapped = 0;
  for i=1:numel(A)-1
    if A(i+1) > A(i)
      memory = A(i);
      A(i) = A(i+1);
      A(i+1) = memory; 
      swapped = 1;
   
    end
  end 
end
disp(A)

A =  [2 9 6 5 8];
n = numel(A);
AA = [A;1:n];
swapped = 1;
while swapped
  swapped = 0;
  for ii = 1:n-1
    if AA(1,ii+1) > AA(1,ii)
      memory = AA(:,ii);
      AA(:,ii) = AA(:,ii+1);
      AA(:,ii+1) = memory; 
      swapped = 1;
    end
  end 
end
Asort = AA(1,:);
Index_sort  = AA(2,:);
