Function Reference

dssdata

Quick access to descriptor state-space data

Syntax

• [a,b,c,d,e] = dssdata(sys)
  [a,b,c,d,e,Ts] = dssdata(sys)
  

Description

[a,b,c,d,e] = dssdata(sys) extracts the descriptor matrix data from the state-space model sys. If sys is a transfer function or zero-pole-gain model, it is first converted to state space. Note that dssdata is then equivalent to ssdata because it always returns .

[a,b,c,d,e,Ts] = dssdata(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.notes
