In control: A Control Systems Toolbox

Description

zp2tf converts the model for a zero-pole-gain system to transfer function representation

Usage

zp2tf(z, p, k)

Arguments

z	A numeric vector containing zero locations
p	A numeric vector containing pole locations
k	A numeric vector for gain

Details

zp2tf converts a model object for a zero-pole-gain system to a transfer function model

Another possible usage is: zp2tf(sys)

where sys is an object of zero-pole-gain model.

Value

Returns a list object of 'tf' class.
