ZGET03

Function/Subroutine Documentation

subroutine ZGET03 (integer n, complex*16, dimension( lda, * ) a, integer lda, complex*16, dimension( ldainv, * ) ainv, integer ldainv, complex*16, dimension( ldwork, * ) work, integer ldwork, double precision, dimension( * ) rwork, double precision rcond, double precision resid)

ZGET03

Purpose:

!>
!> ZGET03 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 COMPLEX*16 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 COMPLEX*16 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 COMPLEX*16 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 )
