OreTools[Modular][GCRD] - compute the GCRD of two Ore polynomials modulo a prime
OreTools[Modular][LCLM] - compute the LCLM of a sequence of Ore polynomials modulo a prime
Calling Sequence
Modular[GCRD](Ore1, Ore2, p, A)
Modular[LCLM](Ore1, Ore2, ..., Orek, p, A)
Parameters
Ore1, Ore2, ... Orek
-
Ore polynomials; to define an Ore polynomial, use the OrePoly structure
p
prime
A
Ore ring; to define an Ore ring, use the SetOreRing command
Description
The Modular[GCRD](Ore1, Ore2, p, A) calling sequence returns the GCRD of Ore1 and Ore2 modulo the prime p.
The Modular[LCLM](Ore1, Ore2, ..., Orek, p, A) calling sequence returns the GCRD of Ore1, Ore2, ..., Orek modulo the prime p.
