Finding Rise Time from System Response

I am trying to find appropriate sample time from the open loop response from my system for use in model predictive control:
A=[-1 1.6 0;0 0 1;0 0 -11.76];
B=[0; 0; 1];
C=[50 0 0];
D=zeros(1,1);
Cont_plant=ss(A,B,C,D); %continuous state space dynamics of plant
step(Cont_plant)
How do i get get the rise time,settling time since this system is not open loop stable? I tried to put it in feedback and still this:
A=[-1 1.6 0;0 0 1;0 0 -11.76];
B=[0; 0; 1];
C=[50 0 0];
D=zeros(1,1);
Cont_plant=ss(A,B,C,D); %continuous state space dynamics of plant
step(Cont_plant)
G=feedback(Cont_plant,1)
step(G)

You can use 'stepinfo' function like below.
A=[-1 1.6 0;0 0 1;0 0 -11.76];
B=[0; 0; 1];
C=[50 0 0];
D=zeros(1,1);
Cont_plant=ss(A,B,C,D); %continuous state space dynamics of plant
step(Cont_plant)
G=feedback(Cont_plant,1);
step(G)
stepinfo(G)
