SYNTAX
  SUBROUTINE DLATZM( SIDE, M, N, V, INCV, TAU, C1, C2, LDC, WORK )

      CHARACTER	     SIDE

      INTEGER	     INCV, LDC, M, N

      DOUBLE	     PRECISION TAU

      DOUBLE	     PRECISION C1( LDC, * ), C2( LDC, * ), V( * ), WORK( * )

DESCRIPTION
  This routine is deprecated and has been replaced by routine DORMRZ.  DLATZM
  applies a Householder matrix generated by DTZRQF to a matrix.

  Let P = I - tau*u*u',	  u = ( 1 ),
			      ( v )
  where v is an (m-1) vector if SIDE = 'L', or a (n-1) vector if SIDE = 'R'.

  If SIDE equals 'L', let
	 C = [ C1 ] 1
	     [ C2 ] m-1
	       n
  Then C is overwritten by P*C.

  If SIDE equals 'R', let
	 C = [ C1, C2 ] m
		1  n-1
  Then C is overwritten by C*P.

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

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

  INCV	  (input) INTEGER
	  The increment between elements of v. INCV <> 0

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

  C1	  (input/output) DOUBLE PRECISION array, dimension
	  (LDC,N) if SIDE = 'L' (M,1)	if SIDE = 'R' On entry, the n-vector
	  C1 if SIDE = 'L', or the m-vector C1 if SIDE = 'R'.

	  On exit, the first row of P*C if SIDE = 'L', or the first column of
	  C*P if SIDE = 'R'.

  C2	  (input/output) DOUBLE PRECISION array, dimension
	  (LDC, N)   if SIDE = 'L' (LDC, N-1) if SIDE = 'R' On entry, the (m
	  - 1) x n matrix C2 if SIDE = 'L', or the m x (n - 1) matrix C2 if
	  SIDE = 'R'.

	  On exit, rows 2:m of P*C if SIDE = 'L', or columns 2:m of C*P if
	  SIDE = 'R'.

  LDC	  (input) INTEGER
	  The leading dimension of the arrays C1 and C2. LDC >= (1,M).

  WORK	  (workspace) DOUBLE PRECISION array, dimension
	  (N) if SIDE = 'L' (M) if SIDE = 'R'
