nmod_mat_scalar_mul

Synopsis#include <flint/nmod_mat.h>
void nmod_mat_scalar_mul(nmod_mat_t B, const nmod_mat_t A, ulong c)source

Sets B=cAB = cA. Requires c<nc < n.

The cases c=0c = 0, 11 and n−1n - 1 are a zeroing, a copy and a negation. Otherwise, for n<2FLINT_BITS−1n < 2^{\mathtt{FLINT\_BITS} - 1} and matrices with at least FLINT_MULMOD_SHOUP_THRESHOLD entries, the products use Shoup multiplication with a quotient precomputed for cc, and nmod_mul otherwise.
