ZHETRS_AA  

Function/Subroutine Documentation

 

subroutine zhetrs_aa (character UPLO, integer N, integer NRHS, complex*16, dimension( lda, * ) A, integer LDA, integer, dimension( * ) IPIV, complex*16, dimension( ldb, * ) B, integer LDB, complex*16, dimension( * ) WORK, integer LWORK, integer INFO)

ZHETRS_AA

Purpose:

 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.


 

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**H;
          = 'L':  Lower triangular, form is A = L*T*L**H.


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 COMPLEX*16 array, dimension (LDA,N)
          Details of factors computed by ZHETRF_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 ZHETRF_AA.


B

          B is COMPLEX*16 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).

 
aram[out] INFO ssful exit < 0: if INFO = -i, the i-th argument had an illegal value
