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.
