pole

Compute poles for a state-space or transfer function model.

Syntax

P = pole(SYS)

Inputs

SYS
State-space or transfer function model.

Outputs

P
The vector of system pole locations.

Examples

Transfer function model input: 
sys_tf = tf([1],[1 3 2]);
P = pole(sys_tf)
P = [Matrix] 2 x 1
-2
-1
State space model input: 
A = [1 2 3; 4 5 6; 7 8 9];
B = [10; 11; 12];
C = [];
D = [];
sys = ss (A, B, C, D);
P = pole(sys)
P = [Matrix] 3 x 1
