ZPOTRI(l)		LAPACK routine (version	1.1)		    ZPOTRI(l)

NAME
  ZPOTRI - compute the inverse of a complex Hermitian positive definite
  matrix A using the Cholesky factorization A =	U**H*U or A = L*L**H computed
  by ZPOTRF

SYNOPSIS

  SUBROUTINE ZPOTRI( UPLO, N, A, LDA, INFO )

      CHARACTER	     UPLO

      INTEGER	     INFO, LDA,	N

      COMPLEX*16     A(	LDA, * )

PURPOSE
  ZPOTRI computes the inverse of a complex Hermitian positive definite matrix
  A using the Cholesky factorization A = U**H*U	or A = L*L**H computed by
  ZPOTRF.

ARGUMENTS

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

  N	  (input) INTEGER
	  The order of the matrix A.  N	>= 0.

  A	  (input/output) COMPLEX*16 array, dimension (LDA,N)
	  On entry, the	triangular factor U or L from the Cholesky factoriza-
	  tion A = U**H*U or A = L*L**H, as computed by	ZPOTRF.	 On exit, the
	  upper	or lower triangle of the (Hermitian) inverse of	A, overwrit-
	  ing the input	factor U or L.

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

  INFO	  (output) INTEGER
	  = 0:	successful exit
	  < 0:	if INFO	= -i, the i-th argument	had an illegal value
	  > 0:	if INFO	= i, the (i,i) element of the factor U or L is zero,
	  and the inverse could	not be computed.
