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
