Function/Subroutine Documentation
subroutine csytrs_aa (character UPLO, integer N, integer NRHS, complex, dimension( lda, * ) A, integer LDA, integer, dimension( * ) IPIV, complex, dimension( ldb, * ) B, integer LDB, complex, dimension( * ) WORK, integer LWORK, integer INFO)
CSYTRS_AA
Purpose:
CSYTRS_AA solves a system of linear equations A*X = B with a complex symmetric matrix A using the factorization A = U*T*U**T or A = L*T*L**T computed by CSYTRF_AA.
- Parameters:
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**T; = 'L': Lower triangular, form is A = L*T*L**T.
N
N is INTEGER The order of the matrix A. N >= 0.
NRHS
NRHS is INTEGER The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
A
A is REAL array, dimension (LDA,N) Details of factors computed by CSYTRF_AA.
LDA
LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N).
IPIV
IPIV is INTEGER array, dimension (N) Details of the interchanges as computed by CSYTRF_AA.
B
B is REAL array, dimension (LDB,NRHS) On entry, the right hand side matrix B. On exit, the solution matrix X.
LDB
LDB is INTEGER The leading dimension of the array B. LDB >= max(1,N).
WORK
WORK is DOUBLE array, dimension (MAX(1,LWORK))
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
