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

Ok then. If S you wrote is a struct, then just write

S.SettlingTime
