Use zpk to create zero-pole-gain models, or to convert dynamic system models to zero-pole-gain form.

Description [z,p,k,dcgain] = zpk (fit) returns the zeros, poles, gain, and DC gain of a rational object. example

Description [z,p,k] = zpk(d) returns the zeros, poles, and gain corresponding to the digital filter, d, in vectors z and p, and scalar k, respectively.

Example 2 Extract the ZPK matrices and their standard deviations for a 2-input, 1 output identified transfer function.

This example shows how to create continuous-time linear models using the tf, zpk, ss, and frd commands.

Compute the zero-pole-gain form of the highpass filter using the zpk function. Design a minimum order highpass FIR filter with a passband frequency of 75 kHz and passband ripple of 0.2 dB.

Use zpk para crear modelos de cero-polo-ganancia o para convertir modelos de sistemas dinámicos al formato de modelo de cero-polo-ganancia.

Use the Model Predictive Control Toolbox zpk function to convert an unconstrained MPC controller with defined sample time to zero/pole/gain form (see mpc for background).

Working with TF and ZPK models often results in high-order polynomials whose evaluation can be plagued by inaccuracies. The TF and ZPK representations are inefficient for manipulating MIMO …

This example shows how to create single-input, single-output (SISO) transfer functions in factored form using zpk. Create the factored transfer function G (s) = 5 s (s + 1 + i) (s + 1 i) (s + 2):
