Function/Subroutine Documentation
   DOUBLE PRECISION function zla_gercond_x (characterTRANS, integerN, complex*16, dimension( lda,
       * )A, integerLDA, complex*16, dimension( ldaf, * )AF, integerLDAF, integer, dimension( *

       ZLA_GERCOND_X computes the infinity norm condition number of op(A)*diag(x) for general
       matrices.

       Purpose:

	       ZLA_GERCOND_X computes the infinity norm condition number of
	       op(A) * diag(X) where X is a COMPLEX*16 vector.

       Parameters:
	   TRANS

		     TRANS is CHARACTER*1
		Specifies the form of the system of equations:
		  = 'N':  A * X = B	(No transpose)
		  = 'T':  A**T * X = B	(Transpose)
		  = 'C':  A**H * X = B	(Conjugate Transpose = Transpose)

	   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 factors L and U from the factorization
		A = P*L*U as computed by ZGETRF.

	   LDAF

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

	   IPIV

		     IPIV is INTEGER array, dimension (N)
		The pivot indices from the factorization A = P*L*U
		as computed by ZGETRF; row i of the matrix was interchanged
		with row IPIV(i).

	   X

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

	   RWORK

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