NAME
TESTING/EIG/zget38.f

SYNOPSIS

  Functions/Subroutines
subroutine zget38 (rmax, lmax, ninfo, knt, nin)
ZGET38

Function/Subroutine Documentation

  subroutine zget38 (double precision, dimension( 3 ) rmax, integer, dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)

ZGET38

Purpose:

     ZGET38 tests ZTRSEN, 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 ZHST01 or comparing
                        different calls to ZTRSEN
              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 ZGEHRD returns INFO nonzero on example i, LMAX(1)=i
              If ZHSEQR returns INFO nonzero on example i, LMAX(2)=i
              If ZTRSEN returns INFO nonzero on example i, LMAX(3)=i

    NINFO

              NINFO is INTEGER array, dimension (3)
              NINFO(1) = No. of times ZGEHRD returned INFO nonzero
              NINFO(2) = No. of times ZHSEQR returned INFO nonzero
              NINFO(3) = No. of times ZTRSEN returned INFO nonzero

    KNT

              KNT is INTEGER
              Total number of examples tested.

    NIN

              NIN is INTEGER
              Input logical unit number.
