it is used only when there is some oscillation before settling.
No, try:
sys=tf([1],[1 1]);
you can check that it is a first order system (no oscillations) with:
step(sys);
and you can retrieve the data you want with:
stepinfo(sys)
ans =
struct with fields:
RiseTime: 2.1970
SettlingTime: 3.9121
SettlingMin: 0.9045
SettlingMax: 1.0000
Overshoot: 0
Undershoot: 0
Peak: 1.0000
PeakTime: 10.5458
