g=input("enter the lowest range of damping factror: ");
wn=input("enter the highest range of natural frequency= ");
%forloop%
for c= g:1
    n=[wn.^2 0 0];
    d=[1 2.*c.*wn wn.^2 ];
    sys=tf(n,d);
    impulse(sys,'r')
    hold on
    g=g+0.1;
 
end

I want to vary the value of damping constant in steps in each response( like 0.1,0.2,0.3, ...... ,1).

so I need to increase the value of given damping rato in steps. but the code is running for only the user input values for once that means onle on plot is showing which is the first case.

so please elp me to solve this one.

Tathagata - if the damping constant/factor is given by g, and you want to increment this value by 0.1 on each iteration of the loop (up to one), then just do

for c= g:0.1:1

where you include the increment of 0.1.
