_D_e_s_c_r_i_p_t_i_o_n:

     Draws picture of one wavelet or scaling function associated with
     the multiple wavelet decomposition object. 'mwd.object'.

_U_s_a_g_e:

     draw.mwd(mwd, phi = 0, psi = 0, return.funct = FALSE, ...)

_A_r_g_u_m_e_n_t_s:

     mwd: The 'mwd' class object whose associated wavelet or scaling
          function you wish to draw. 

     phi: description not yet available

     psi: If 'phi' is non-zero then the `phi'-th scaling function of
          the wavelet family used for mwd will be plotted. 'phi' must
          be between 0 and 'mwd$filter$nphi'.

return.funct: If true then the vector used as phi/psi in the plot
          command is returned.

     ...: Additional arguments to pass to the 'plot' function

_D_e_t_a_i_l_s:

     It is usual to specify just one of phi and psi. IF neither phi nor
     psi are specified then phi=1 is the default. An error is generated
     if both phi=0 and psi=0 or if both are nonzero.

_V_a_l_u_e:

     If the 'return.funct' argument is set to 'TRUE' then the function
     values in the plot are returned otherwise 'NULL' is returned.

_R_E_L_E_A_S_E:

     Version 3.9.6 (Although Copyright Tim Downie 1995-6).
