Synopsis
#include <flint/fmpq_mat.h>void fmpq_mat_mul(fmpq_mat_t C, const fmpq_mat_t A, const fmpq_mat_t B)sourcevoid fmpq_mat_mul_cleared(fmpq_mat_t C, const fmpq_mat_t A, const fmpq_mat_t B)sourcevoid fmpq_mat_mul_direct(fmpq_mat_t C, const fmpq_mat_t A, const fmpq_mat_t B)sourceSets . fmpq_mat_mul calls fmpq_mat_mul_cleared, which clears denominators of the rows of and of the columns of , multiplies the integer matrices with fmpz_mat_mul and divides entry by the product of the -th row and -th column denominators. fmpq_mat_mul_direct computes the dot products in rational arithmetic and throws if is or . fmpq_mat_mul and fmpq_mat_mul_cleared allow aliasing.
