I want to write a code for the attached file.

tau=10;

>> Tf=100;

>> sys = tf(1,[1.7*10^-12,1.6*10^-6,1])

sys =

1

---------------------------

1.7e-12 s^2 + 1.6e-06 s + 1

Continuous-time transfer function.

>> [u0,t] = gensig("square",tau,Tf);

u = 2*u0-1;

>> lsim(sys,u,t)

Tried using this nut does not work can some body help me with it.

Hi

I assume the signal shown in the image is the input signal. I think whatever you are doing is correct, you might be getting same curve with slight shift of 1 time unit with same magnitude. It may be because of the transfer function you have selected as its coefficients are very small. Try with different transfer function like

tau=10;
Tf=100;
sys = tf(1,[1,10]);
[u0,t] = gensig("square",tau,Tf);
u = 2*u0-1;
lsim(sys,u,t)

You will see a significant change in response. Hope it will help!
