IMC (internal model control) structure with connect command

Hi I want to implement the IMC structure as shown in the picture below. I was wondering if the following code is correct ? Because it seems that it's not. Thanks

P = tf([1],[1 1]); P.InputName = 'u'; P.OutputName = 'y';

M = tf([1],[1 1]); M.InputName = 'u'; M.OutputName = 'ym';

Q = tf([1 1],[2 1]); Q.InputName = 'e'; Q.OutputName = 'u';

Sum1 = sumblk('d = y - ym'); Sum2 = sumblk('e = r - d');

T = connect(Q,M,P,Sum1,Sum2,'r','y');
