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

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

but i'm not using any transfer function model...frequency is an array from iterative procedure i have an array..

Consider this approach:

Gs=tf(1,[1 1]); 
result=stepinfo(Gs); 
SettlingTime=result.SettlingTime

thankyou for responding

but my output is an array it came form iterative procedure not from transfer function approach

[POLURI SRIMANNARAYANA]

yes yes got it

THANKYOU SO MUCH sir

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

S.SettlingTime
