       ZLA_SYRCOND_C computes the infinity norm condition number of op(A)*inv(diag(c)) for symmetric indefinite matrices.

       Purpose:

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

       Parameters:
	   UPLO

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

	   N

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

	   A

		     A is COMPLEX*16 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*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

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

	   IPIV

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

	   C

		     C is DOUBLE PRECISION 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.

	   WORK

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

	   RWORK

		     RWORK is DOUBLE PRECISION array, dimension (N).
		Workspace.
