CGET38

Function/Subroutine Documentation

subroutine cget38 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)

CGET38

Purpose:

 CGET38 tests CTRSEN, 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 CHST01 or comparing
                    different calls to CTRSEN
          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 CGEHRD returns INFO nonzero on example i, LMAX(1)=i
          If CHSEQR returns INFO nonzero on example i, LMAX(2)=i
          If CTRSEN returns INFO nonzero on example i, LMAX(3)=i

NINFO

          NINFO is INTEGER array, dimension (3)
          NINFO(1) = No. of times CGEHRD returned INFO nonzero
          NINFO(2) = No. of times CHSEQR returned INFO nonzero
          NINFO(3) = No. of times CTRSEN returned INFO nonzero

KNT

          KNT is INTEGER
          Total number of examples tested.

NIN

          NIN is INTEGER
          Input logical unit number.
