Function Documentation

mzd_t* _mzd_addmul_mp4	(	mzd_t *	C,
		mzd_t const *	A,
		mzd_t const *	B,
		int	cutoff
	)

Matrix multiplication and in-place addition via cubic matrix multiplication algorithm on up to four cores, i.e. compute C = C+ AB.

Parameters

C	Product matrix
A	Input matrix A
B	Input matrix B
cutoff	Minimal dimension for recursion.

mzd_t* _mzd_mul_mp4	(	mzd_t *	C,
		mzd_t const *	A,
		mzd_t const *	B,
		int	cutoff
	)

Matrix multiplication via cubic matrix multiplication algorithm on up to four cores, i.e. compute C = C+ AB.

Parameters

C	Product matrix
A	Input matrix A
B	Input matrix B
cutoff	Minimal dimension for recursion.

mzd_t* mzd_addmul_mp	(	mzd_t *	C,
		mzd_t const *	A,
		mzd_t const *	B,
		int	cutoff
	)

Matrix multiplication and in-place addition via the cubic matrix multiplication algorithm on multiple cores, i.e. compute C = C+ AB.

This is the wrapper function including bounds checks. See _mzd_addmul_mp4 for implementation details.

Parameters

C	product matrix
A	Input matrix A
B	Input matrix B
cutoff	Minimal dimension for recursion.

Examples:

testsuite/test_multiplication.c.

mzd_t* mzd_mul_mp	(	mzd_t *	C,
		mzd_t const *	A,
		mzd_t const *	B,
		int	cutoff
	)

Matrix multiplication via the cubic multiplication algorithm on multiple cores, i.e. compute C = AB.

This is the wrapper function including bounds checks. See _mzd_mul_mp4 for implementation details.

Parameters

C	Preallocated product matrix, may be NULL for automatic creation.
A	Input matrix A
B	Input matrix B
cutoff	Minimal dimension for recursion.

Examples:

testsuite/test_multiplication.c.
