zpkdata
Extracts data from a zero-pole-gain model.
Syntax
[Z, P, K, Ts] = zpkdata(SYS)
Inputs
- SYS
- Zero-pole-gain data model.
Outputs
- Z
- A vector containing the zeros of the system.
- P
- A vector containing the poles of the system.
- K
- A scalar, the gain of the system.
- Ts
- Sampling time (in seconds).
Examples
Example 1:
sys = zpk([1 -2], [-1,-2+i,-2-i], 10, 12);
[z, p, k, Ts] = zpkdata(sys)[z, p, k, Ts] = zpkdata(sys)
z =
{
[1,1] z = [Matrix] 1 x 2
1 -2
}
}
p =
{
[1,1] p = [Matrix] 1 x 3
-1 + 0i -2 + 1i -2 - 1i
}
}
k = 10
Ts = 12
Example 2:
sys = zpk([], [], 7);
[z, p, k, Ts] = zpkdata(sys)z =
{
[1,1] z = [Matrix] 0 x 1
}
p =
{
[1,1] p = [Matrix] 0 x 1
}
k = 7
Ts = -2
Comments
[Z, P, K, Ts] = zpkdata(SYS) returns the zeros, poles, and gain parameters of the zero, pole, gain model SYS.
