(polynomial) state-space to descriptor form
S = ss2des(Sl) S = ss2des(Sl, flag)
syslin
list: proper or improper linear system.
character string "withD"
list
Given the linear system in state-space representation
Sl
(syslin
list), with a D
matrix which is either
polynomial or constant, but not zero ss2des
returns a descriptor system as list('des',A,B,C,0,E)
such that:
If the flag "withD"
is given, S=list('des',A,B,C,D,E)
with a D
matrix of maximal rank.
