           CSPTRS

Function/Subroutine Documentation
   subroutine csptrs (character uplo, integer n, integer nrhs, complex,
       dimension( * ) ap, integer, dimension( * ) ipiv, complex, dimension(
       ldb, * ) b, integer ldb, integer info)
       CSPTRS

       Purpose:


           !>
           !> CSPTRS solves a system of linear equations A*X = B with a complex
           !> symmetric matrix A stored in packed format using the factorization
           !> A = U*D*U**T or A = L*D*L**T computed by CSPTRF.
           !>

       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*D*U**T;
           !>          = 'L':  Lower triangular, form is A = L*D*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.
           !>

           AP

           !>          AP is COMPLEX array, dimension (N*(N+1)/2)
           !>          The block diagonal matrix D and the multipliers used to
           !>          obtain the factor U or L as computed by CSPTRF, stored as a
           !>          packed triangular matrix.
           !>

           IPIV

           !>          IPIV is INTEGER array, dimension (N)
           !>          Details of the interchanges and the block structure of D
           !>          as determined by CSPTRF.
           !>

           B

           !>          B is COMPLEX 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).
           !>

           INFO

           !>          INFO is INTEGER
           !>          = 0:  successful exit
           !>          < 0: if INFO = -i, the i-th argument had an illegal value
           !>
