◆ core_zhetf2sp()

static void core_zhetf2sp ( pastix_int_t  n,
pastix_complex64_t *  A,
pastix_int_t  lda,
pastix_int_t *  nbpivots,
double  criterion 
)
inlinestatic

Compute the sequential static pivoting factorization of the hermitian matrix n-by-n A such that A = L * D * conj(L^t).

Parameters
[in]nThe number of rows and columns of the matrix A.
[in,out]AThe matrix A to factorize with LDL^h factorization. The matrix is of size lda -by- n.
[in]ldaThe leading dimension of the matrix A.
[in,out]nbpivotsPointer to the number of piovting operations made during factorization. It is updated during this call
[in]criterionThreshold use for static pivoting. If diagonal value is under this threshold, its value is replaced by the threshold and the number of pivots is incremented.
