What is z plane in Matlab?

zplane( z , p ) plots the zeros specified in column vector z and the poles specified in column vector p in the current figure window. The symbol 'o' represents a zero and the symbol 'x' represents a pole. The plot includes the unit circle for reference.

Where is Z plane?

The Z-plane is a complex plane with an imaginary and real axis referring to the complex-valued variable z. The position on the complex plane is given by reiθ and the angle from the positive, real axis around the plane is denoted by θ.

How do you plot Z transform in Matlab?

Specify Independent Variable and Transformation Variable

Compute the Z-transform of exp(m+n) . By default, the independent variable is n and the transformation variable is z . Specify the transformation variable as y . If you specify only one variable, that variable is the transformation variable.

How to use ZPK in Matlab?

sys = zpk( zeros , poles , gain ) creates a continuous-time zero-pole-gain model with zeros and poles specified as vectors and the scalar value of gain . The output sys is a zpk model object storing the model data. Set zeros or poles to [] for systems without zeros or poles.
