SRC/cpotri.f(3) Library Functions Manual SRC/cpotri.f(3) NAME SRC/cpotri.f SYNOPSIS Functions/Subroutines subroutine cpotri (uplo, n, a, lda, info) CPOTRI Function/Subroutine Documentation subroutine cpotri (character uplo, integer n, complex, dimension( lda, * ) a, integer lda, integer info) CPOTRI 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. 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 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 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.
