           DSYCONV

Function/Subroutine Documentation
   subroutine dsyconv (character uplo, character way, integer n, double
       precision, dimension( lda, * ) a, integer lda, integer, dimension( * )
       ipiv, double precision, dimension( * ) e, integer info)
       DSYCONV

       Purpose:


           !>
           !> DSYCONV convert A given by TRF into L and D and vice-versa.
           !> Get Non-diag elements of D (returned in workspace) and
           !> apply or reverse permutation done in TRF.
           !>

       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.
           !>

           WAY

           !>          WAY is CHARACTER*1
           !>          = 'C': Convert
           !>          = 'R': Revert
           !>

           N

           !>          N is INTEGER
           !>          The order of the matrix A.  N >= 0.
           !>

           A

           !>          A is DOUBLE PRECISION array, dimension (LDA,N)
           !>          The block diagonal matrix D and the multipliers used to
           !>          obtain the factor U or L as computed by DSYTRF.
           !>

           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 DSYTRF.
           !>

           E

           !>          E is DOUBLE PRECISION array, dimension (N)
           !>          E stores the supdiagonal/subdiagonal of the symmetric 1-by-1
           !>          or 2-by-2 block diagonal matrix D in LDLT.
           !>

           INFO

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