Synopsis
#include <flint/gr_poly.h>int _gr_poly_precompute_matrix(gr_mat_t A, gr_srcptr f, gr_srcptr g, slong leng, gr_srcptr ginv, slong lenginv, gr_ctx_t ctx)sourceint gr_poly_precompute_matrix(gr_mat_t A, const gr_poly_t f, const gr_poly_t g, const gr_poly_t ginv, gr_ctx_t ctx)sourceSet row i of A to f^i \bmod g for 0 \le i < m, m = \lfloor \sqrt{\deg g} \rfloor + 1, the baby steps of Brent-Kung modular composition with argument f and modulus g. A must have exactly m rows and \deg g columns (GR_DOMAIN otherwise, for the non-underscore version), g must be nonzero and ginv must be the inverse of the reversal of g.
