NAME
TESTING/EIG/zget37.f

SYNOPSIS

  Functions/Subroutines
subroutine zget37 (rmax, lmax, ninfo, knt, nin)
ZGET37

Function/Subroutine Documentation

  subroutine zget37 (double precision, dimension( 3 ) rmax, integer, dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)

ZGET37

Purpose:

     ZGET37 tests ZTRSNA, 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 DOUBLE PRECISION array, dimension (3)
              Value of the largest test ratio.
              RMAX(1) = largest ratio comparing different calls to ZTRSNA
              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 ZTRSNA 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 ZTRSNA returned INFO nonzero

    KNT

              KNT is INTEGER
              Total number of examples tested.

    NIN

              NIN is INTEGER
              Input logical unit number
