Functions for Galois field calculations
int2poly(x, gf)poly2int(poly, gf)
gf_sum(x, y, gf)
gf_prod(x, y, gf)
gf_sum_list(ll, gf, checks = TRUE)
gf_matmult(M1, M2, gf, checks = TRUE)
int2poly returns an e x n matrix or a length n vector (if x is scalar)
poly2int returns an e element vector of integers in 0:(q-1)
gf_sum returns the sum (e elements in 0:(q-1))
gf_prod returns the product (e elements in 0:(q-1))
gf_sum_list returns the sum (an integer vector in 0:(q-1))
gf_matmult returns the matrix product with elements from 0:(q-1)
a vector of e elements in 0:(q-1)
Galois field object with characteristic q
