NAME

       zlarfx.f -

SYNOPSIS

   Functions/Subroutines
       subroutine zlarfx (SIDE, M, N, V, TAU, C, LDC, WORK)
	   ZLARFX

Function/Subroutine Documentation
   subroutine zlarfx (characterSIDE, integerM, integerN, complex*16, dimension( * )V, complex*16TAU, complex*16, dimension( ldc, * )C, integerLDC,
       complex*16, dimension( * )WORK)
       ZLARFX

       Purpose:

	    ZLARFX 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*16 array, dimension (M) if SIDE = 'L'
						   or (N) if SIDE = 'R'
		     The vector v in the representation of H.

	   TAU

		     TAU is COMPLEX*16
		     The value tau in the representation of H.

	   C

		     C is COMPLEX*16 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*16 array, dimension (N) if SIDE = 'L'
						       or (M) if SIDE = 'R'
		     WORK is not referenced if H has order < 11.

NAME

       clarf.f -

SYNOPSIS

   Functions/Subroutines
       subroutine clarf (SIDE, M, N, V, INCV, TAU, C, LDC, WORK)
	   CLARF

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

       Purpose:

	    CLARF 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.

	    To apply H**H (the conjugate transpose of H), supply conjg(tau) instead
	    tau.

       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
				(1 + (M-1)*abs(INCV)) if SIDE = 'L'
			     or (1 + (N-1)*abs(INCV)) if SIDE = 'R'
		     The vector v in the representation of H. V is not used if
		     TAU = 0.

	   INCV

		     INCV is INTEGER
		     The increment between elements of v. INCV <> 0.

	   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. LDC >= max(1,M).

	   WORK

		     WORK is COMPLEX array, dimension
				    (N) if SIDE = 'L'
				 or (M) if SIDE = 'R'
