zp2tf

Zero-pole to transfer function conversion.

📝Syntax

[NUM, DEN] = zp2tf(Z, P, K)

📥Input Arguments

Parameter	Description
Z	Locations of zeros, organized in columns for each system output.
P	Locations of poles, recorded as a column vector.
K	Gains.

📤Output Arguments

Parameter	Description
NUM	Coefficients in the numerator, organized by rows corresponding to each system output.
DEN	Coefficients in the denominator, arranged as a row vector.

📄Description

[NUM, DEN] = zp2tf(Z, P, K) returns polynomial transfer function representation from zeros and poles.

💡Examples

p = [0.5;0.45+0.5i;0.45-0.5i];
z = [-1;i;-i];       
k = 1;
[n, d] = zp2tf(z, p, k)
