NAME
TESTING/EIG/sget38.f

SYNOPSIS

  Functions/Subroutines
subroutine sget38 (rmax, lmax, ninfo, knt, nin)
SGET38

Function/Subroutine Documentation

  subroutine sget38 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)

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.
