NAME

/home/abuild/rpmbuild/BUILD/lapack-3.12.0/TESTING/EIG/cget37.f

SYNOPSIS

Functions/Subroutines


subroutine CGET37 (rmax, lmax, ninfo, knt, nin)
CGET37

Function/Subroutine Documentation

subroutine CGET37 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)

CGET37

Purpose:

!>
!> CGET37 tests CTRSNA, a routine for estimating condition numbers of
!> eigenvalues and/or right eigenvectors of a matrix.
!>
!> The test matrices are read from a file with logical unit number NIN.
!> 

Parameters

RMAX

!>          RMAX is REAL array, dimension (3)
!>          Value of the largest test ratio.
!>          RMAX(1) = largest ratio comparing different calls to CTRSNA
!>          RMAX(2) = largest error in reciprocal condition
!>                    numbers taking their conditioning into account
!>          RMAX(3) = largest error in reciprocal condition
!>                    numbers not taking their conditioning into
!>                    account (may be larger than RMAX(2))
!> 

LMAX

!>          LMAX is INTEGER array, dimension (3)
!>          LMAX(i) is example number where largest test ratio
!>          RMAX(i) is achieved. Also:
!>          If CGEHRD returns INFO nonzero on example i, LMAX(1)=i
!>          If CHSEQR returns INFO nonzero on example i, LMAX(2)=i
!>          If CTRSNA returns INFO nonzero on example i, LMAX(3)=i
!> 

NINFO

!>          NINFO is INTEGER array, dimension (3)
!>          NINFO(1) = No. of times CGEHRD returned INFO nonzero
!>          NINFO(2) = No. of times CHSEQR returned INFO nonzero
!>          NINFO(3) = No. of times CTRSNA returned INFO nonzero
!> 

KNT

!>          KNT is INTEGER
!>          Total number of examples tested.
!> 

NIN

!>          NIN is INTEGER
!>          Input logical unit number
!>
