  Consider a multivariable state space system and associated transfer function
G({\lambda}). The aim of this paper is to define and analyze two vector spaces
of matrix pencils associated with the matrix G({\lambda}) and show that almost
all of these pencils are linearizations of G({\lambda}). We also construct
symmetric/Hermitian linearizations of G({\lambda}) when G({\lambda}) is regular
and symmetric/Hermitian.
