TESTING/EIG/cget37.f

SYNOPSIS

  Functions/Subroutines
subroutine cget37 (rmax, lmax, ninfo, knt, nin)
CGET37

Function/Subroutine Documentation

  subroutine cget37 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)

CGET37

Purpose:

     CGET37 tests CTRSNA, 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 REAL array, dimension (3)
              Value of the largest test ratio.
              RMAX(1) = largest ratio comparing different calls to CTRSNA
              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 CTRSNA 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 CTRSNA returned INFO nonzero

    KNT

              KNT is INTEGER
              Total number of examples tested.

    NIN

              NIN is INTEGER
              Input logical unit number
