SRC/dpotri.f(3) Library Functions Manual SRC/dpotri.f(3) NAME SRC/dpotri.f SYNOPSIS Functions/Subroutines subroutine dpotri (uplo, n, a, lda, info) DPOTRI Function/Subroutine Documentation subroutine dpotri (character uplo, integer n, double precision, dimension( lda, * ) a, integer lda, integer info) DPOTRI Purpose: !> !> DPOTRI computes the inverse of a real symmetric positive definite !> matrix A using the Cholesky factorization A = U**T*U or A = L*L**T !> computed by DPOTRF. !> 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 DOUBLE PRECISION array, dimension (LDA,N) !> On entry, the triangular factor U or L from the Cholesky !> factorization A = U**T*U or A = L*L**T, as computed by !> DPOTRF. !> On exit, the upper or lower triangle of the (symmetric) !> 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. !> Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
