/*  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' */
