ZHETRS_AA solves a system of linear equations A*X = B with a complex hermitian matrix A using the factorization A = U*T*U**H or A = L*T*L**T computed by ZHETRF_AA.
[in] | UPLO | 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*T*U**H; = 'L': Lower triangular, form is A = L*T*L**H. |
[in] | N | N is INTEGER The order of the matrix A. N >= 0. |
[in] | NRHS | NRHS is INTEGER The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0. |
[in,out] | A | A is COMPLEX*16 array, dimension (LDA,N) Details of factors computed by ZHETRF_AA. |
[in] | LDA | LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N). |
[in] | IPIV | IPIV is INTEGER array, dimension (N) Details of the interchanges as computed by ZHETRF_AA. |
[in,out] | B | B is COMPLEX*16 array, dimension (LDB,NRHS) On entry, the right hand side matrix B. On exit, the solution matrix X. |
[in] | LDB | LDB is INTEGER The leading dimension of the array B. LDB >= max(1,N). |
[in] | WORK | WORK is DOUBLE array, dimension (MAX(1,LWORK)) |
[in] | LWORK | LWORK is INTEGER, LWORK >= MAX(1,3*N-2). \param[out] INFO \verbatim INFO is INTEGER = 0: successful exit < 0: if INFO = -i, the i-th argument had an illegal value |
