Function File: [a, b, c, d, tsam] = ssdata (sys)

Access state-space model data. Argument sys is not limited to state-space models. If sys is not a state-space model, it is converted automatically.

Inputs

sys

Any type of LTI model.

Outputs

a

State matrix (n-by-n).

b

Input matrix (n-by-m).

c

Measurement matrix (p-by-n).

d

Feedthrough matrix (p-by-m).

tsam

Sampling time in seconds. If sys is a continuous-time model, a zero is returned.

Note on compatibility

If sys is given by an input-output description, like, e.g., a transfer function, the resulting state-space model has a different form than the one provided by Matlab, see ss for details.
