NAME
TESTING/EIG/zget36.f

SYNOPSIS

  Functions/Subroutines
subroutine zget36 (rmax, lmax, ninfo, knt, nin)
ZGET36

Function/Subroutine Documentation

  subroutine zget36 (double precision rmax, integer lmax, integer ninfo, integer knt, integer nin)

ZGET36

Purpose:

    !>
    !> ZGET36 tests ZTREXC, a routine for reordering diagonal entries of a
    !> matrix in complex Schur form. Thus, ZLAEXC computes a unitary matrix
    !> Q such that
    !>
    !>    Q' * T1 * Q  = T2
    !>
    !> and where one of the diagonal blocks of T1 (the one at row IFST) has
    !> been moved to position ILST.
    !>
    !> The test code verifies that the residual Q'*T1*Q-T2 is small, that T2
    !> is in Schur form, and that the final position of the IFST block is
    !> ILST.
    !>
    !> The test matrices are read from a file with logical unit number NIN.

Parameters
    RMAX

    !>          RMAX is DOUBLE PRECISION
    !>          Value of the largest test ratio.
    !>

    LMAX

    !>          LMAX is INTEGER
    !>          Example number where largest test ratio achieved.
    !>

    NINFO

    !>          NINFO is INTEGER
    !>          Number of examples where INFO is nonzero.
    !>

    KNT

    !>          KNT is INTEGER
    !>          Total number of examples tested.
    !>

    NIN

    !>          NIN is INTEGER
    !>          Input logical unit number.
