NAME
TESTING/EIG/sget32.f

SYNOPSIS

  Functions/Subroutines
subroutine sget32 (rmax, lmax, ninfo, knt)
SGET32

Function/Subroutine Documentation

  subroutine sget32 (real rmax, integer lmax, integer ninfo, integer knt)

SGET32

Purpose:

    !>
    !> SGET32 tests SLASY2, a routine for solving
    !>
    !>         op(TL)*X + ISGN*X*op(TR) = SCALE*B
    !>
    !> where TL is N1 by N1, TR is N2 by N2, and N1,N2 =1 or 2 only.
    !> X and B are N1 by N2, op() is an optional transpose, an
    !> ISGN = 1 or -1. SCALE is chosen less than or equal to 1 to
    !> avoid overflow in X.
    !>
    !> The test condition is that the scaled residual
    !>
    !> norm( op(TL)*X + ISGN*X*op(TR) = SCALE*B )
    !>      / ( max( ulp*norm(TL), ulp*norm(TR)) * norm(X), SMLNUM )
    !>
    !> should be on the order of 1. Here, ulp is the machine precision.
    !> Also, it is verified that SCALE is less than or equal to 1, and
    !> that XNORM = infinity-norm(X).
    !>

Parameters
    RMAX

    !>          RMAX is REAL
    !>          Value of the largest test ratio.
    !>

    LMAX

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

    NINFO

    !>          NINFO is INTEGER
    !>          Number of examples returned with INFO.NE.0.
    !>

    KNT

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