/*  -- LAPACK auxiliary routine (version 3.1) --   
       Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..   
       November 2006   


    Purpose   
    =======   

    DLARFX applies a real elementary reflector H to a real m by n   
    matrix C, from either the left or the right. H is represented in the   
    form   

          H = I - tau * v * v'   

    where tau is a real scalar and v is a real vector.   

    If tau = 0, then H is taken to be the unit matrix   

    This version uses inline code if H has order < 11.   

    Arguments   
    =========   

    SIDE    (input) CHARACTER*1   
            = 'L': form  H * C   
            = 'R': form  C * H   

    M       (input) INTEGER   
            The number of rows of the matrix C.   

    N       (input) INTEGER   
            The number of columns of the matrix C.   

    V       (input) DOUBLE PRECISION array, dimension (M) if SIDE = 'L'   
                                       or (N) if SIDE = 'R'   
            The vector v in the representation of H.   

    TAU     (input) DOUBLE PRECISION   
            The value tau in the representation of H.   

    C       (input/output) DOUBLE PRECISION array, dimension (LDC,N)   
            On entry, the m by n matrix C.   
            On exit, C is overwritten by the matrix H * C if SIDE = 'L',   
            or C * H if SIDE = 'R'.   

    LDC     (input) INTEGER   
            The leading dimension of the array C. LDA >= (1,M).   

    WORK    (workspace) DOUBLE PRECISION array, dimension   
                        (N) if SIDE = 'L'   
                        or (M) if SIDE = 'R'   
            WORK is not referenced if H has order < 11.
