NAME
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 !>
