zpkdata
retrieves a model object for a zero-pole-gain system, from a sys
object of tf
, ss
and zpk
classes
Returns a list object of zpk
class containing zero, pole and gain matrices. For multivariable systems,
the zeros of each system is listed as a column in the zeros matrix, the poles are listed as a column-vector as well as the
gain
