zp2ss
Convert zero-pole-gain filter parameters to state-space form
Syntax
Description
[
finds a state-space representationA
,B
,C
,D
] = zp2ss(z
,p
,k
)
such that it is equivalent to a system in factored transfer function form
Column vector p
specifies the pole locations, and matrix
z
the zero locations with as many columns as there are outputs. The
gains for each numerator transfer function are in vector k
. The
A
, B
, C
, and
D
matrices are returned in controller canonical form.

zp2ss
, for single-input systems, groups complex pairs together into
two-by-two blocks down the diagonal of the A
matrix. This requires the
zeros and poles to be real or complex conjugate pairs.
