NAME
       clarfx.f -

SYNOPSIS
   Functions/Subroutines
       subroutine clarfx (SIDE, M, N, V, TAU, C, LDC, WORK)
	   CLARFX

Function/Subroutine Documentation
   subroutine clarfx (characterSIDE, integerM, integerN, complex, dimension( * )V, complexTAU, complex, dimension( ldc, * )C, integerLDC, complex,
       dimension( * )WORK)
       CLARFX

       Purpose:

	    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**H

	    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.

       Parameters:
	   SIDE

		     SIDE is CHARACTER*1
		     = 'L': form  H * C
		     = 'R': form  C * H

	   M

		     M is INTEGER
		     The number of rows of the matrix C.

	   N

		     N is INTEGER
		     The number of columns of the matrix C.

	   V

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

	   TAU

		     TAU is COMPLEX
		     The value tau in the representation of H.

	   C

		     C is 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

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

	   WORK

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