Function/Subroutine Documentation¶
subroutine DGET03 (integer n, double precision, dimension( lda, * ) a, integer lda, double precision, dimension( ldainv, * ) ainv, integer ldainv, double precision, dimension( ldwork, * ) work, integer ldwork, double precision, dimension( * ) rwork, double precision rcond, double precision resid)¶
DGET03
Purpose:
!> !> DGET03 computes the residual for a general matrix times its inverse: !> norm( I - AINV*A ) / ( N * norm(A) * norm(AINV) * EPS ), !> where EPS is the machine epsilon. !>
Parameters
N
!> N is INTEGER !> The number of rows and columns of the matrix A. N >= 0. !>
A
!> A is DOUBLE PRECISION array, dimension (LDA,N) !> The original N x N matrix A. !>
LDA
!> LDA is INTEGER !> The leading dimension of the array A. LDA >= max(1,N). !>
AINV
!> AINV is DOUBLE PRECISION array, dimension (LDAINV,N) !> The inverse of the matrix A. !>
LDAINV
!> LDAINV is INTEGER !> The leading dimension of the array AINV. LDAINV >= max(1,N). !>
WORK
!> WORK is DOUBLE PRECISION array, dimension (LDWORK,N) !>
LDWORK
!> LDWORK is INTEGER !> The leading dimension of the array WORK. LDWORK >= max(1,N). !>
RWORK
!> RWORK is DOUBLE PRECISION array, dimension (N) !>
RCOND
!> RCOND is DOUBLE PRECISION !> The reciprocal of the condition number of A, computed as !> ( 1/norm(A) ) / norm(AINV). !>
RESID
!> RESID is DOUBLE PRECISION !> norm(I - AINV*A) / ( N * norm(A) * norm(AINV) * EPS ) !>
