SYNOPSIS
Functions/Subroutines
subroutine dget38 (rmax, lmax, ninfo, knt, nin)
DGET38
Function/Subroutine Documentation
subroutine dget38 (double precision, dimension( 3 ) rmax, integer, dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)
DGET38
Purpose:
DGET38 tests DTRSEN, a routine for estimating condition numbers of a cluster of eigenvalues and/or its associated right invariant subspace The test matrices are read from a file with logical unit number NIN.
Parameters
RMAX
RMAX is DOUBLE PRECISION array, dimension (3) Values of the largest test ratios. RMAX(1) = largest residuals from DHST01 or comparing different calls to DTRSEN 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 DGEHRD returns INFO nonzero on example i, LMAX(1)=i If DHSEQR returns INFO nonzero on example i, LMAX(2)=i If DTRSEN returns INFO nonzero on example i, LMAX(3)=i
NINFO
NINFO is INTEGER array, dimension (3) NINFO(1) = No. of times DGEHRD returned INFO nonzero NINFO(2) = No. of times DHSEQR returned INFO nonzero NINFO(3) = No. of times DTRSEN returned INFO nonzero
KNT
KNT is INTEGER Total number of examples tested.
NIN
NIN is INTEGER Input logical unit number.
