_D_e_s_c_r_i_p_t_i_o_n:

     Extend the data as the exponential of base N by increasing row
     number.

_U_s_a_g_e:

     extendNBase(x, nLevel=1, base=2, ...) 

_A_r_g_u_m_e_n_t_s:

       x: data matrix 

  nLevel: the level of DWT decomposition. Basically, it is equivalent
          to changing the 'base' as base\^nLevel

    base: the base, 2 by default 

     ...: other parameters of used by 'extendLength' 

_D_e_t_a_i_l_s:

     The method 'open' is padding the the matrix with the last row.

_V_a_l_u_e:

     Return a extended matrix

_A_u_t_h_o_r(_s):

     Pan Du

_S_e_e _A_l_s_o:

     'extendLength'

_E_x_a_m_p_l_e_s:

             # a = matrix(rnorm(9), 3)
             # extendNBase(a)        ## not exposed function
