NAME
       clatzm.f -

SYNOPSIS
   Functions/Subroutines
       subroutine clatzm (SIDE, M, N, V, INCV, TAU, C1, C2, LDC, WORK)
	   CLATZM

Function/Subroutine Documentation
   subroutine clatzm (characterSIDE, integerM, integerN, complex, dimension( *
       )V, integerINCV, complexTAU, complex, dimension( ldc, * )C1, complex,
       dimension( ldc, * )C2, integerLDC, complex, dimension( * )WORK)
       CLATZM

       Purpose:

	    This routine is deprecated and has been replaced by routine CUNMRZ.

	    CLATZM applies a Householder matrix generated by CTZRQF to a matrix.

	    Let P = I - tau*u*u**H,   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.

       Parameters:
	   SIDE

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

	   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'
			     (1 + (N-1)*abs(INCV)) if SIDE = 'R'
		     The vector v in the representation of P. 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 P.

	   C1

		     C1 is COMPLEX 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

		     C2 is COMPLEX 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

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

	   WORK

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