MATLAB Program for finding Poles & Zeroes of Transfer Function

Q. The transfer function of a system is given below

Determines the poles and zeroes and show the pole-zero configuration in s-plane using MATLAB.

First of all simplifying numerator(p1) and denominator(q1) of the transfer function respectively as

p1=8s²+56s+96

q1=s⁴+4s³+9s²+10s
