MATLAB: Result of stepinfo size is 1×1 …how can i extract settling time to another variable

settlingtime

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
