 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
