Hello, I want to pot only the unit step in matlab with this code:
s=tf('s')
sys=1/s
I expectet the step response like this:
But i get a plot in matlab like this:
Why do I get a step response like the second picture. Should a step input it not look like my first picture? Thanks

Hi @Mark S
System 1:
s = tf('s');
sys1 = 1/s; % integrator system
step(sys1)
System 2:
sys2 = zpk([], [], 1) % just a static gain
step(sys2)

Because that's what the step response of the transfer function you mentioned looks like.
You might be looking for heaviside
syms x
fplot(heaviside(x), [-5, 5],"LineWidth",1.5)
ylim([0 1.5])
