issiso
Checks if an LTI model is single-input/single-output (SISO)
Syntax
B = issiso(SYSIN)
Inputs
- SYSIN
- A state-space or transfer function model.
Outputs
- B
- A scalar. 0 (not SISO) or 1 (SISO).
Examples
State-space model as input to the function:
A = [0 1;-5 -2];
B = [0;3];
C = [0 1];
D = 0;
sys = ss(A, B, C, D, 0.25);
issiso(sys)ans = 1Transfer function model as input to the function:
N1 = [1 -1];
N2 = [1];
N3 = [1 2];
N4 = [3 1 4];
N = {N1, N2; N3, N4};
D = [1 1 10];
H = tf(N, D);

issiso(SYS) checks if an LTI model is single-input/single-output (SISO).
