Pseudoremainder

Computes the pseudo-remainder of two polynomials. Given two polynomials $P$ and $Q$ with degrees $p$ and $q$, respectively; the pseudo-remainder of $P$ and $Q$ is defined as

$pseudoremainder(P,Q)=remainder\left(leading\_coefficient(Q{)}^{p-q+1}·P,Q\right)$

pseudoremainder(Polynomial, Polynomial)

Description

Given two polynomials $P$ and $Q$, returns the pseudoremainder.
