Matrix produces 12 times

I wrote a for function to create a 4 by 3 matrix. When I run it, I get the right matrix, but it copies 12 times. Why is this? What do I need to change?

for i = 1:4;
    for j = 1:3;
        A(i,j) = (50*i/(2077*273*j))

      end;
  end;

Add a semi-colon after the assignment statement.

Note: that is the only place the semi-colon is meaningful in your code.

for i = 1:4
  for j = 1:3
      A(i,j) = (50*i/(2077*273*j));

      end
  end

Is there any way of displaying this in the command window only once?

 for i = 1:4
  for j = 1:3
      A(i,j) = (50*i/(2077*273*j));
      end
  end
