Function/Subroutine Documentation
   subroutine chetrs2 (character uplo, integer n, integer nrhs, complex,
       dimension( lda, * ) a, integer lda, integer, dimension( * ) ipiv,

       Purpose:


           !>
           !> CHETRS2 solves a system of linear equations A*X = B with a complex
           !> Hermitian matrix A using the factorization A = U*D*U**H or
           !> A = L*D*L**H computed by CHETRF and converted by CSYCONV.
           !>

       Parameters

           !>          UPLO is CHARACTER*1

           !>          = 'U':  Upper triangular, form is A = U*D*U**H;

           !>          The block diagonal matrix D and the multipliers used to
           !>          obtain the factor U or L as computed by CHETRF.
           !>

           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 and the block structure of D
           !>          as determined by CHETRF.
