ZLATZM - routine is deprecated and has been replaced by
routine ZUNMRZ
SYNOPSIS
SUBROUTINE ZLATZM( SIDE, M, N, V, INCV, TAU, C1, C2, LDC,
WORK )
CHARACTER SIDE
INTEGER INCV, LDC, M, N
COMPLEX*16 TAU
COMPLEX*16 C1( LDC, * ), C2( LDC, * ), V( * ),
WORK( * )
PURPOSE
This routine is deprecated and has been replaced by rou
tine ZUNMRZ. ZLATZM applies a Householder matrix gener
ated by ZTZRQF 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) vec
tor 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) COMPLEX*16 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.
The increment between elements of v. INCV <> 0
TAU (input) COMPLEX*16
The value tau in the representation of P.
C1 (input/output) COMPLEX*16 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) COMPLEX*16 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 >= max(1,M).
WORK (workspace) COMPLEX*16 array, dimension
(N) if SIDE = 'L' (M) if SIDE = 'R'
