conj - Form model with complex conjugate coefficients

Syntax

sysc = conj(sys)

Description

sysc = conj(sys) constructs a complex conjugate model sysc by applying complex conjugation to all coefficients of the LTI model sys. This function accepts LTI models in transfer function (TF), zero/pole/gain (ZPK), and state space (SS) formats.

Example

If sys is the transfer function

(2+i)/(s+i)

then conj(sys) produces the transfer function

(2-i)/(s-i)

This operation is useful for manipulating partial fraction expansions.
