NAME
TESTING/EIG/dget38.f

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.
