 *  Purpose  
 *  =======  
 *  
 *  ZSYCONV converts A given by ZHETRF into L and D or vice-versa.  
 *  Get nondiagonal elements of D (returned in workspace) and   
 *  apply or reverse permutation done in TRF.  
 *  
 *  Arguments  
 *  =========  
 *  
 *  UPLO    (input) 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     (input) CHARACTER*1  
 *          = 'C': Convert   
 *          = 'R': Revert  
 *  
 *  N       (input) INTEGER  
 *          The order of the matrix A.  N >= 0.  
 *  
 *  A       (input) DOUBLE COMPLEX array, dimension (LDA,N)  
 *          The block diagonal matrix D and the multipliers used to  
 *          obtain the factor U or L as computed by ZSYTRF.  
 *  
 *  LDA     (input) INTEGER  
 *          The leading dimension of the array A.  LDA >= max(1,N).  
 *  
 *  IPIV    (input) INTEGER array, dimension (N)  
 *          Details of the interchanges and the block structure of D  
 *          as determined by ZSYTRF.  
 *  
 * WORK     (workspace) DOUBLE COMPLEX array, dimension (N)  
 *  
 * LWORK    (input) INTEGER  
 *          The length of WORK.  LWORK >=1.   
 *          LWORK = N  
 *  
 *          If LWORK = -1, then a workspace query is assumed; the routine  
 *          only calculates the optimal size of the WORK array, returns  
 *          this value as the first entry of the WORK array, and no error  
 *          message related to LWORK is issued by XERBLA.  
 *  
 *  INFO    (output) INTEGER  
 *          = 0:  successful exit  
 *          < 0:  if INFO = -i, the i-th argument had an illegal value
