函数名称：ld monic, log-based representation of a polynomial

函数原型：static void gf_poly_logrep(struct bch_control *bch, const struct gf_poly *a, int *rep)

返回类型：void

参数：

类型参数名称
struct bch_control *bch
const struct gf_poly *a
int *rep
712  d等于polynomial degree , l等于GF_N(bch)减a_log(bch, polynomial terms [polynomial degree ])
715  以i小于d循环rep[i]等于如果polynomial terms [i]则shorter and faster modulo function, only works when v < 2N.否则负1
