How does this matlab function works?

If I give an input delay of 0.1350 to the state space system, it doesn't make any difference to the system's response

ss_model=ss(A,B,C,D,'InputDelay',0.1350)

Someone please explain how this function works or in what cases, this function fits in exactly.

This is not true

%-----------------model without delay-----------
A=[-11 1;-10 0];B=[0;1];C=[1 0];D=0;
ss_model1=ss(A,B,C,D)
subplot(2,1,1);
step(ss_model1)
%-----------------model wit delay----------------
retard=2
subplot(2,1,2);
ss_model2=ss(A,B,C,D,'InputDelay',retard)
step(ss_model2)

Thank you. But can you please tell me what would be the command if the delay is being given to the second input signal .

Look at this MIMO system

A=[-11 1;-10 0];
B=[0 0;1 1];
C=[1 0;0 1];
D=zeros(2);
ss_model1=ss(A,B,C,D)
ss_model1.InputDelay(2)=2 %  delay the second input
step(ss_model1)
