NAME

       LAPACK-3  -  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 CPOTRF

SYNOPSIS

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

           CHARACTER      UPLO

           INTEGER        INFO, LDA, N

           COMPLEX        A( LDA, * )

PURPOSE

       CPOTRI 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 CPOTRF.

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 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
                CPOTRF.
                On exit, the upper or lower triangle of the (Hermitian)
                inverse of A, overwriting 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.
