Algobra: Conway polynomials

This package contains the list of Conway polynomials provided on the homepage of Frank Lübeck.

If desired, the package can be used on its own by utilizing Lookup, which is the only exported function. The return value is the slice uints representing the coefficients of the Conway polynomial.

Overview

Package conway contains a database of Conway polynomials. The list of polynomials was compiled by Frank Lübeck: http://www.math.rwth-aachen.de/~Frank.Luebeck/data/ConwayPol/index.html?LANG=en

Example

package main

import (
	"fmt"

	"github.com/ReneBoedker/algobra/finitefield/conway"
)

func main() {
	coefs, err := conway.Lookup(3, 5)
	if err != nil {
		return
	}

	fmt.Println(coefs)
}

Output:

[1 2 0 0 0 1]

Functions

func Lookup

func Lookup(char, extDeg uint) (coefs []uint, err error)

Lookup returns the coefficients for a Conway polynomial for the finite field of characteristic char and extension degree extDeg. The element at position i is the coefficient of X^i.

If no such polynomial is in the database, an InputValue-error is returned.
