Hi,
My state space system contains 6 outputs and some of them's first values are not zero. In my opinion, when t=0; first values of outputs should be zero, but step command doesn't give me all of them as 0.
It may be because of D, but i'm not sure.
Is there any point which i miss? How can i make first values of y1 an y4 zero? Can it be possible?
Thanks,
clear all

A=[-7.4 -10.6;-0.7 -16.9];

C=[-7.4 0;0 1;1 0;-0.1 -0.14;-0.1 0.13;0.1 0];
D=[37.3;0;0;1;0;0];
sys=ss(A,B,C,D);
t=0:0.01:10;
[y,t]=step(sys,t)
