is it possible to visualize poles and zeros of any transfer function in MATLAB????? and if possible can someone suggest how to go about it as i have never used matlab .....is their some simple way to do my analysis where is simple put positions of poles and zeros of my system in it and it shows me 3D diagrams of these P-Z in s-plane.
 

I believe that PZMAP is the matlab command you are looking for.

thanks

can u tell how to use this command?
do i need to give transfer function in matlab or can simply giving positions of poles and zeros will be enough???
 

you will give the transfer function in matlab
use like that to get the transfer function
sys = tf(num,den)
then
pzmap(sys)

it's ok
