Plotting multiple Values on one axis

I need to plot a variety of numerator values for a single denominator value.

The numerator values needed are 0.1, 1, 10, 100, 1000. If possible on individual graphs for each numerator value

Given formula = k/s+a

Where num = k and den = s+a

Given K values to be (0.1, 1, 10, 100, 1000) and a (0.1, 1, 10, 100, 1000), with all k values to be plotted for each value of a

This is my best attempt at a single value for k. Is this right?

num=[0.1];

den=[1 0.1];

G=tf(num,den);

CIsys=feedback(G,1)

step(CIsys)

title('Step response of 0.1/(s+0.1)')

subplot(2,2,1),step(G),title('Step response 0.1/s+0.1')

grid on

subplot(2,2,2),impulse(G),title('Impulse Response 0.1/s+0.1')

grid on

subplot(2,2,3),pzmap(G),title('Pole-zero map 0.1/s+0.1')

grid on

subplot(2,2,4),margin(G),title('Bode Diagram 0.1/s+0.1')

grid on

num=[0.1, 1, 10, 100, 1000];
den=[1 0.1];
for i=1:length(num)
G=tf(num(i),den);
CIsys=feedback(G,1)
step(CIsys)
title('Step response of 0.1/(s+0.1)');
step(G), hold on, title('Step response 0.1/s+0.1')
end

Do modification for all plots, I have shown one here

Worked perfectly thank you!

Good to hear that, it works @Tom
