Plotting equation for certain values

Given the equation -k/(s+a)

For k values (0.1, 1, 10, 100, 1000) Plot impulse and bode responses and pole-zero maps (can be either individual figures or combined figures)

For a values (0.1, 1, 10, 100, 1000) Plot impulse, step and Bode Responses and pole-zero maps (can be either individual figures or combined figures)

And what is your question? You seem to have just pasted a homework question in verbatim, adding nothing to it at all!

Even where to start would be great, no backgeound or introduction to MATLAB was given and i am struggling to even get started with this.

Thanks

Have a look on matlab help files about the following functions:

• tf : how to define a transfer function on s or z plane
• bodeplot
• feedback
• pzplot

For example, you maybe have to write some code like this:

clear all; close all; clc;

k=1;
a=5;
Hs=tf( k,[1 a])

figure; 
bode(Hs); 
grid on;
