subroutine sget38 (rmax, lmax, ninfo, knt, nin)
SGET38

SGET38

Purpose:

 SGET38 tests STRSEN, 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 REAL array, dimension (3)
          Values of the largest test ratios.
          RMAX(1) = largest residuals from SHST01 or comparing
                    different calls to STRSEN
          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 SGEHRD returns INFO nonzero on example i, LMAX(1)=i
          If SHSEQR returns INFO nonzero on example i, LMAX(2)=i
          If STRSEN returns INFO nonzero on example i, LMAX(3)=i

NINFO

          NINFO is INTEGER array, dimension (3)
          NINFO(1) = No. of times SGEHRD returned INFO nonzero
          NINFO(2) = No. of times SHSEQR returned INFO nonzero
          NINFO(3) = No. of times STRSEN returned INFO nonzero

KNT

          KNT is INTEGER
          Total number of examples tested.

NIN

          NIN is INTEGER
          Input logical unit number.
