PURPOSE
       slatzm routine is deprecated and has been replaced by routine SORMRZ.

       SLATZM applies a Householder matrix generated by STZRQF 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)
                 = 'L': form P * C
                 = 'R': form C * P


       M (input) The number of rows of the matrix C.


       N (input) The number of columns of the matrix C.


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


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


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


       WORK (workspace)
                 (N) if SIDE = 'L' (M) if SIDE = 'R'
