Sorting columns of a matrix without sort()

I have a 15x10 matrix with random generated integers between 0 and 100. I have to sort the columns in ascending order using a bubble sort algorithm. I am not supposed to use sort(). I have no clue how to even start.

Thank you everbody for your help!

Thanks, but I understand how to use bubblesort for rows but I don't understand how to transfer it to sorting columns of a matrix

Once you have done it for a row, you can just use a for loop.

M; % matrix

for i = 1:size(M,2)
    col = M(:,i);
    % apply sorting algorithm on col
    M(:,i) = col;
end

Thank you! That helped me finding the answer!
