how can i find the lsim info for this transfer function

i'm trying to find lsim info for this transfer function, i know the code

s=lsiminfo

this code is like

stepinfo(sys)

which is great, but i need to use lsim.

this is my Matlab program:

G=tf([],[]);    % ANY KIND OF TRANSFER FUNCTION
t=0:0.001:1;
u=100*heaviside(t);     % Step in 100 level
lsim(G,u,t)             % Liniar Simulation
LsimInfo=lsiminfo(G)

i need relevant data for both the Heaviside (step) that applied into the transfer function but i don't know how to get this info.

what do you mean by

 G = tf(1,[1 2 5]); % whatever your transfer function is
 t=0:0.001:1;
 u=100*heaviside(t);     % Step in 100 level
 resp = lsim(G,u,t);
 S = lsiminfo(resp,t);

The above user resp(end) as the steady-state value.
