subroutine dget10 (m, n, a, lda, b, ldb, work, result)
DGET10

DGET10

Purpose:

!>
!> DGET10 compares two matrices A and B and computes the ratio
!> RESULT = norm( A - B ) / ( norm(A) * M * EPS )
!> 

Parameters

M
!>          M is INTEGER
!>          The number of rows of the matrices A and B.
!> 

N

!>          N is INTEGER
!>          The number of columns of the matrices A and B.
!> 

A

!>          A is DOUBLE PRECISION array, dimension (LDA,N)
!>          The m by n matrix A.
!> 

LDA

!>          LDA is INTEGER
!>          The leading dimension of the array A.  LDA >= max(1,M).
!> 

B

!>          B is DOUBLE PRECISION array, dimension (LDB,N)
!>          The m by n matrix B.
!> 

LDB

!>          LDB is INTEGER
!>          The leading dimension of the array B.  LDB >= max(1,M).
!> 

WORK

!>          WORK is DOUBLE PRECISION array, dimension (M)
!> 

RESULT

!>          RESULT is DOUBLE PRECISION
!>          RESULT = norm( A - B ) / ( norm(A) * M * EPS )
!>
