Re: Partial Fraction Decomposition in c++

Hello! In order to calculate the Amplitude of a pole of an ARMA filter, I
realise that I have to do a partial fraction decomposition (PFD) of the
ARMA filter transfer function.

The PFD has to be done, so that I can calculate the residuum of the
transfer function at each pole.

I have the transfer function and have calculated the roots of the
numerator and denominator polynomials, but have totally no idea how to
implement the the PFD.

I'm not quite sure what you mean by "Amplitude of a pole" - but once
you have the roots of the numerator and denominator polynomials, you
have pretty much all the information you can get from this transfer
function (up to a scaling factor). Perhaps you meant the magnitudes of
the poles?
