Sum of products of discrete-time polynomials by their adjoints.
Syntax
Description
If P1,P2,... are vectors of coefficients representing discrete-time polynomials
, then this function returns one half of the mirror-image discrete-time polynomial obtained by multiplying polynomials
by their adjoints
and adding them together.
If P1,P2,... are polynomial matrices in in Polynomial Toolbox format, then Q is a para-hermitian polynomial matrix corresponding to the summation
. The necessary shifts are performed on the input arguments to make the output para-hermitian. Pure delays are also accounted for. In case the additional input argument ‘cof’ is used, the output changes to
The routine is normally used together with spectral factorization routines spfz, spf and spcof.
