result of stepinfo size is 1x1 ...how can i extract settling time to another variable

13 views (last 30 days)
my objective is to minimize the settling time....so at each and every time have to calculate settling time...for that am using stepinfo syntax
result is coming like below
S = RiseTime: 0.0015
SettlingTime: 17.4555
SettlingMin: 48.2799
SettlingMax: 50.7285
Overshoot: 1.4607
Undershoot: 0
Peak: 50.7285_
PeakTime: 5.9900
so how can i take settlingTime or any value to another variable
am grateful to u if u respond _____________THANKING YOU

Consider this approach:
Gs=tf(1,[1 1]);
result=stepinfo(Gs);
SettlingTime=result.SettlingTime
