Purpose 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.Ifsys 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 in addition
to
a, b, c, d,ande.
You can access the remaining LTI properties of
sys with get or by direct
referencing, for example,
sys.notes
