Hello, I have this transfer function:
sys = tf([2],[1 2]) G(s)
And this is my step input signal:
R(s)= 2/s
How can i combine R(s) and G(s) and plot this.
When I write this in Matlab i can plot only the transfer function withouz my step input singal:
sys = tf([2],[1 2]) G(s)
step(sys)
stepinfo(sys)

You can multiplythem together and then use the impulse() function
s = tf('s');
G = 2/(s+2);
R = 2/s;
sys = G*R;
impulse(sys)
