       subroutine clatzm (side, m, n, v, incv, tau, c1, c2, ldc, work)
           CLATZM

Function/Subroutine Documentation
   subroutine clatzm (character side, integer m, integer n, complex,
       dimension( * ) v, integer incv, complex tau, complex, dimension( ldc, *
       ) c1, complex, dimension( ldc, * ) c2, integer ldc, complex, dimension(
       * ) work)
       CLATZM

       Purpose:


            This routine is deprecated and has been replaced by routine CUNMRZ.

            CLATZM applies a Householder matrix generated by CTZRQF 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.

       Parameters

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