While loop shows the result of the previous run

So I'm currently working on a code for rank order clustering method, the issue I have is that I have to calculate once for the rows reorder them to descend then calculate the columns and reorder them to descent again. on my last run on the while loop the rows had to be reordered but the columns didnt have to, so the while loop was broken but it shows the matrix that was in the previous run. I've attached the code

    % Check if there's any change in the matrix positions
    previous_matrix = matrix; % Store the previous matrix
    
    % Check for convergence
    if isequal(previous_matrix, matrix)
        change = false;
    end
    

If you set previous_matrix to matrix before you check if they are equal, then (since they are set before to be equal) "change" will become "false" immediately after the first loop through the "while" statement.
