!> 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.

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
