subroutine zget38 (rmax, lmax, ninfo, knt, nin)
ZGET38

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.
