NAME
       dsyconv.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dsyconv (UPLO, WAY, N, A, LDA, IPIV, WORK, INFO)
	   DSYCONV

Function/Subroutine Documentation
   subroutine dsyconv (characterUPLO, characterWAY, integerN, double precision, dimension( lda, * )A, integerLDA, integer, dimension( * )IPIV,
       double precision, dimension( * )WORK, integerINFO)
       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.

	   WORK

		     WORK is DOUBLE PRECISION array, dimension (N)

	   INFO

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