Function/Subroutine Documentation
   REAL function cla_porcond_x (characterUPLO, integerN, complex, dimension(
       lda, * )A, integerLDA, complex, dimension( ldaf, * )AF, integerLDAF,
       complex, dimension( * )X, integerINFO, complex, dimension( * )WORK,
       real, dimension( * )RWORK)
       CLA_PORCOND_X computes the infinity norm condition number of
       op(A)*diag(x) for Hermitian positive-definite matrices.

       Purpose:

	       CLA_PORCOND_X Computes the infinity norm condition number of
	       op(A) * diag(X) where X is a COMPLEX 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 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).

	   X

		     X is COMPLEX array, dimension (N)
		The vector X in the formula op(A) * diag(X).

	   INFO

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

	   WORK

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

	   RWORK

		     RWORK is REAL array, dimension (N).
		Workspace.
