FQ_MAT_MUL_KS_CUTOFF

Synopsis#include <flint/fq_mat.h>
int FQ_MAT_MUL_KS_CUTOFF(slong r, slong c, const fq_ctx_t ctx)source

Returns 1 if fq_mat_mul should use Kronecker substitution for an r×kr \times k times k×ck \times c product, which is the case if 5min⁡(r,c)>8d+295 \min(r, c) > 8d + 29. (FQ_NMOD_MAT_MUL_KS_CUTOFF and FQ_ZECH_MAT_MUL_KS_CUTOFF are the corresponding tuned functions of the other representations.)
