Function/Subroutine Documentation
   subroutine dlatzm (character side, integer m, integer n, double precision,
       dimension( * ) v, integer incv, double precision tau, double precision,
       dimension( ldc, * ) c1, double precision, dimension( ldc, * ) c2,
       integer ldc, double precision, dimension( * ) work)
       DLATZM

       Purpose:


            This routine is deprecated and has been replaced by routine DORMRZ.

            DLATZM applies a Householder matrix generated by DTZRQF 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.

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