How do you make a pole-zero plot in Matlab?
To create pole-zero maps with default options or to extract pole-zero data, use pzmap . h = pzplot( sys ) plots the poles and transmission zeros of the dynamic system model sys and returns the plot handle h to the plot. x and o indicates poles and zeros respectively.
What is pole-zero plot theory?
In mathematics, signal processing and control theory, a pole–zero plot is a graphical representation of a rational transfer function in the complex plane which helps to convey certain properties of the system such as: Stability. Causal system / anticausal system.
Why do we plot poles and zeros?
Pole-Zero plot is an important tool, which helps us to relate the Frequency domain and Z-domain representation of a system. Understanding this relation will help in interpreting results in either domain. It also helps in determining stability of a system, given its transfer function H(z).
