ssdata

Quick access to state-space model data

Syntax

[a,b,c,d] = ssdata(sys)
[a,b,c,d,Ts] = ssdata(sys)

Description

[a,b,c,d] = ssdata(sys) extracts the matrix (or multidimensional array) data from the state-space model (LTI array) sys. If sys is a transfer function or zero-pole-gain model (LTI array), it is first converted to state space. See Table 11-16, "State-Space Model Properties," on page 11-195 for more information on the format of state-space model data.

[a,b,c,d,Ts] = ssdata(sys) also returns the sample time Ts.

You can access the remaining LTI properties of sys with get or by direct referencing, for example,

sys.statename
