 ZLATZM applies a Householder matrix generated by ZTZRQF 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.

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*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.

INCV

          INCV is INTEGER


          The increment between elements of v. INCV <> 0

TAU

          TAU is COMPLEX*16


          The value tau in the representation of P.

C1

          C1 is 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

          C2 is 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

          LDC is INTEGER


          The leading dimension of the arrays C1 and C2.


          LDC >= max(1,M).

WORK

          WORK is COMPLEX*16 array, dimension


                      (N) if SIDE = 'L'


                      (M) if SIDE = 'R'
