SYNOPSIS
   Functions/Subroutines
       subroutine slatzm (side, m, n, v, incv, tau, c1, c2, ldc, work)
           SLATZM

Function/Subroutine Documentation
   subroutine slatzm (character side, integer m, integer n, real, dimension( *
       ) v, integer incv, real tau, real, dimension( ldc, * ) c1, real,
       dimension( ldc, * ) c2, integer ldc, real, dimension( * ) work)
       SLATZM

       Purpose:


            This routine is deprecated and has been replaced by routine SORMRZ.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**T,   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

                     The vector v in the representation of P. V is not used
                     if TAU = 0.

           INCV

                     INCV is INTEGER

                     TAU is REAL
                     The value tau in the representation of P.

           C1

                     C1 is REAL array, dimension
                                    (LDC,N) if SIDE = 'L'

                     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'.
