How we can get z transform in factored form if we have z,p and k?I have also attached snapshot of z transform below
I can use matlab command tf2zp for finding z,p and k.
(z,p,k)=tf2zp(n,d) where n=numerator of H(z) and d=denominator of H(z)
But from there onwards how can i then proceed to find factored form?
Is it better to use matlab function zp2sos ??
