Synopsis
#include <flint/gr_poly.h>int _gr_poly_mullow(gr_ptr res, gr_srcptr poly1, slong len1, gr_srcptr poly2, slong len2, slong len, gr_ctx_t ctx)sourceint gr_poly_mullow(gr_poly_t res, const gr_poly_t poly1, const gr_poly_t poly2, slong len, gr_ctx_t ctx)sourceSets res to the product truncated to length len, that is reduced modulo x^{\mathit{len}}. The underscore version requires positive lengths and \mathit{len} \le \mathit{len1} + \mathit{len2} - 1, writes len coefficients and does not allow aliasing. It calls the ring method GR_METHOD_POLY_MULLOW, which defaults to classical multiplication and which most rings with fast multiplication override.
