Detailed Description

Function Documentation

int plasma_clauum	(	plasma_enum_t	uplo,
		int	n,
		plasma_complex32_t *	pA,
		int	lda
	)

Computes the product U * U^H or L^H * L, where the triangular factor U or L is stored in the upper or lower triangular part of the array A.

If uplo = 'U' or 'u' then the upper triangle of the result is stored, overwriting the factor U in A. If uplo = 'L' or 'l' then the lower triangle of the result is stored, overwriting the factor L in A.

Parameters

[in]	uplo	PlasmaUpper: Upper triangle of A is stored; PlasmaLower: Lower triangle of A is stored.
[in]	n	The order of the matrix A. n >= 0.
[in,out]	pA	On entry, the triangular factor U or L. On exit, if UPLO = 'U', the upper triangle of A is overwritten with the upper triangle of the product U * U^H; if UPLO = 'L', the lower triangle of A is overwritten with the lower triangle of the product L^H * L. The diagonal is assumed to be real with no imaginary part.
[in]	lda	The leading dimension of the array A. lda >= max(1,n).

Return values

PlasmaSuccess	successful exit.
<	0 if -i, the i-th argument had an illegal value.

void plasma_omp_clauum	(	plasma_enum_t	uplo,
		plasma_desc_t	A,
		plasma_sequence_t *	sequence,
		plasma_request_t *	request
	)

Computes the product U * U^H or L^H * L, where the triangular factor U or L is stored in the upper or lower triangular part of the array A.

Parameters

[in]	uplo	PlasmaUpper: Upper triangle of A is stored; PlasmaLower: Lower triangle of A is stored.
[in]	A	Descriptor of matrix A.
[in]	sequence	Identifies the sequence of function calls that this call belongs to (for completion checks and exception handling purposes). Check the sequence->status for errors.
[out]	request	Identifies this function call (for exception handling purposes).

Return values

void	Errors are returned by setting sequence->status and request->status to error values. The sequence->status and request->status should never be set to PlasmaSuccess (the initial values) since another async call may be setting a failure value at the same time.
