PURPOSE
  CLARFX - applie a complex elementary reflector H to a complex m by n matrix
  C, from either the left or the right

SYNTAX
  SUBROUTINE CLARFX( SIDE, M, N, V, TAU, C, LDC, WORK )

      CHARACTER	     SIDE

      INTEGER	     LDC, M, N

      COMPLEX	     TAU

      COMPLEX	     C( LDC, * ), V( * ), WORK( * )

DESCRIPTION
  CLARFX applies a complex elementary reflector H to a complex 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 complex scalar and v is a complex 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) COMPLEX array, dimension (M) if SIDE = 'L'
	  or (N) if SIDE = 'R' The vector v in the representation of H.

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

  C	  (input/output) COMPLEX 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 >= max(1,M).

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