Display Loop Values in a Matrix?

I have a loop that is supposed to calculate a matrix. Which it does right, but it does not print how I want it too. I show my code and how it prints now.

    for y=0:n-1;
          Cm=A.^y;
          C=Cm(n)*B;
          disp(C)
    end

    Answer

     2

     6
     6
     6

    18
    18
    18

I want the results to display like this

ans =

       2     6    18
       2     6    18
       2     6    18

but no matter what I try I cannot get it to do so. Any help would be greatly appreciated. Thank you.

One way is to just collect the values into a matrix inside the loop and display outside

 C = zeros(3,3);
 for n = 1:9

    C(n) = randi(5,1,1);
 end
 fprintf('%d\t %d\t %d\n',C);
 % or disp(C)

You actually don't need to even set it up as a matrix first:

 C = zeros(9,1);
 for n = 1:9

    C(n) = randi(5,1,1);
 end
 fprintf('%d\t %d\t %d\n',C);

If you want to print it out in the loop, you can do something like

   C = zeros(9,1);
   for n = 1:9

      C(n) = randi(5,1,1);
      if (mod(n,3)~=0)
      fprintf('%d \t',C(n));
      else
          fprintf('%d\n',C(n));
      end
   end
