How do I remove the dotted steady state line from the step response plot? I used the step() command to plot the step response of 94 transfer function in one plot.

I use the step() command to plot the step response of 94 transfer function in one plot.

I want to remove the dotted lines.

You can add one more step and assign the step response to a variable and then plot it:

sys = tf([8 18 32],[1 6 14 24])
y = step(sys)
plot(y)

Thanks Mark, it works.

y=zeros(196,94);
for j=1:94
y1=step(H(j));
y(:,j)=y1;
end

figure()
plot(y)
