ZLA_SYRPVGRW computes the reciprocal pivot growth factor
 norm(A)/norm(U). The "max absolute element" norm is used. If this is
 much less than 1, the stability of the LU factorization of the
 (equilibrated) matrix A could be poor. This also means that the
 solution X, estimated condition numbers, and error bounds could be
 unreliable.

          UPLO is CHARACTER*1
       = 'U':  Upper triangle of A is stored;
       = 'L':  Lower triangle of A is stored.

          N is INTEGER
     The number of linear equations, i.e., the order of the
     matrix A.  N >= 0.

          INFO is INTEGER
     The value of INFO returned from ZSYTRF, .i.e., the pivot in
     column INFO is exactly 0.

          A is COMPLEX*16 array, dimension (LDA,N)
     On entry, the N-by-N matrix A.

          LDA is INTEGER
     The leading dimension of the array A.  LDA >= max(1,N).

          AF is COMPLEX*16 array, dimension (LDAF,N)
     The block diagonal matrix D and the multipliers used to
     obtain the factor U or L as computed by ZSYTRF.

          LDAF is INTEGER
     The leading dimension of the array AF.  LDAF >= max(1,N).

          IPIV is INTEGER array, dimension (N)
     Details of the interchanges and the block structure of D
     as determined by ZSYTRF.

          WORK is COMPLEX*16 array, dimension (2*N)
