       CLA_PORCOND_C computes the infinity norm condition number of op(A)*inv(diag(c)) for
       Hermitian positive-definite matrices.

       Purpose:

               CLA_PORCOND_C Computes the infinity norm condition number of
               op(A) * inv(diag(C)) where C is a DOUBLE PRECISION vector

                     N is INTEGER
                The number of linear equations, i.e., the order of the

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

           LDA

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

           AF

                     AF is COMPLEX array, dimension (LDAF,N)
                The triangular factor U or L from the Cholesky factorization
                A = U**H*U or A = L*L**H, as computed by CPOTRF.

           LDAF

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

           C

                     C is REAL array, dimension (N)
                The vector C in the formula op(A) * inv(diag(C)).

           CAPPLY

                     CAPPLY is LOGICAL
                If .TRUE. then access the vector C in the formula above.

           INFO

                     INFO is INTEGER
                  = 0:  Successful exit.
                i > 0:  The ith argument is invalid.
