void hetrs_aa(char *uplo, integer *n, integer *nrhs, T *a, integer *lda, integer *ipiv, T *b, integer *ldb, T *work, integer *lwork, integer *info)# HETRS_AA solves a system of linear equations A*X = B with a complex hermitian matrix A.
Purpose:
HETRS_AA solves a system of linear equations A*X = B with a complex hermitian matrix A using the factorization A = U**H*T*U or A = L*T*L**H computed by HETRF_AA.
- Parameters:
UPLO – [in]
UPLO is CHARACTER*1
Specifies whether the details of the factorization are stored as an upper or lower triangular matrix.
= ‘U’: Upper triangular, form is A = U**H*T*U;
= ‘L’: Lower triangular, form is A = L*T*L**H.
N – [in]
N is INTEGER
The order of the matrix A. N >= 0.
NRHS – [in]
NRHS is INTEGER
The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
A – [in]
A is COMPLEX array, dimension (LDA,N)
Details of factors computed by CHETRF_AA.
LDA – [in]
LDA is INTEGER
The leading dimension of the array A. LDA >= fla_max(1,N).
IPIV – [in]
IPIV is INTEGER array, dimension (N)
Details of the interchanges as computed by CHETRF_AA.
B – [inout]
B is COMPLEX array, dimension (LDB,NRHS)
On entry, the right hand side matrix B. On exit, the solution matrix X.
LDB – [in]
LDB is INTEGER
The leading dimension of the array B. LDB >= fla_max(1,N).
WORK – [out] WORK is COMPLEX array, dimension (MAX(1,LWORK))
LWORK – [in]
LWORK is INTEGER
The dimension of the array WORK. LWORK >= fla_max(1,3*N-2).
INFO – [out]
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
