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.

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.
