MATLAB: How can i sort columns of a matrix in ascending order using loops without using the functions max,min,sort

Question

I have a 15×10 matrix with numbers and i need to sort each column in ascending order

Answer 1

Here's a really simple, inefficient way:

M = rand(15,10)
for col = 1:size(M,2)
    for iters = 1:size(M,1)
        for row = 1:(size(M,1)-1)
            if (M(row,col) > M(row+1,col))
                temp = M(row,col);
                M(row,col) = M(row+1,col);
                M(row+1,col) = temp;
            end
        end
    end
end
M
