Detailed Description

Function Documentation

magma_clauum()

magma_int_t magma_clauum	(	magma_uplo_t	uplo,
		magma_int_t	n,
		magmaFloatComplex *	A,
		magma_int_t	lda,
		magma_int_t *	info )

CLAUUM 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 = MagmaUpper then the upper triangle of the result is stored, overwriting the factor U in A. If UPLO = MagmaLower then the lower triangle of the result is stored, overwriting the factor L in A. This is the blocked form of the algorithm, calling Level 3 BLAS.

Parameters

[in]	uplo	magma_uplo_t Specifies whether the triangular factor stored in the array A is upper or lower triangular: = MagmaUpper: Upper triangular = MagmaLower: Lower triangular
[in]	n	INTEGER The order of the triangular factor U or L. N >= 0.
[in,out]	A	COMPLEX array, dimension (LDA,N) On entry, the triangular factor U or L. On exit, if UPLO = MagmaUpper, the upper triangle of A is overwritten with the upper triangle of the product U * U^H; if UPLO = MagmaLower, the lower triangle of A is overwritten with the lower triangle of the product L^H * L.
[in]	lda	INTEGER The leading dimension of the array A. LDA >= max(1,N).
[out]	info	INTEGER = 0: successful exit < 0: if INFO = -k, the k-th argument had an illegal value
