NAME¶
/home/abuild/rpmbuild/BUILD/lapack-3.12.0/TESTING/EIG/sget37.f
SYNOPSIS¶
Functions/Subroutines¶
subroutine SGET37 (rmax, lmax, ninfo, knt, nin)
SGET37
Function/Subroutine Documentation¶
subroutine SGET37 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)¶
SGET37
Purpose:
!> !> SGET37 tests STRSNA, 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 STRSNA !> 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 SGEHRD returns INFO nonzero on example i, LMAX(1)=i !> If SHSEQR returns INFO nonzero on example i, LMAX(2)=i !> If STRSNA returns INFO nonzero on example i, LMAX(3)=i !>
NINFO
!> NINFO is INTEGER array, dimension (3) !> NINFO(1) = No. of times SGEHRD returned INFO nonzero !> NINFO(2) = No. of times SHSEQR returned INFO nonzero !> NINFO(3) = No. of times STRSNA returned INFO nonzero !>
KNT
!> KNT is INTEGER !> Total number of examples tested. !>
NIN
!> NIN is INTEGER !> Input logical unit number !>
