SRC/zpotri.f(3)            Library Functions Manual            SRC/zpotri.f(3)

NAME
       SRC/zpotri.f

SYNOPSIS
   Functions/Subroutines
       subroutine zpotri (uplo, n, a, lda, info)
           ZPOTRI

Function/Subroutine Documentation
   subroutine zpotri (character uplo, integer n, complex*16, dimension( lda, *
       ) a, integer lda, integer info)
       ZPOTRI

       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.

       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 order of the matrix A.  N >= 0.

           A

                     A is COMPLEX*16 array, dimension (LDA,N)
                     On entry, the triangular factor U or L from the Cholesky
                     factorization 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, overwriting the input factor U or L.

           LDA

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

           INFO

                     INFO is 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.
