_D_e_s_c_r_i_p_t_i_o_n_:

     Compute degrees of freedom for wavelet thresholding
     model.

_U_s_a_g_e_:

     dof(wd)

_A_r_g_u_m_e_n_t_s_:

      wd: The wavelet object

_D_e_t_a_i_l_s_:

     The wavelet thresholding is a non-linear transform and
     dof returns the approximate number of degrees of free-
     dom.

_V_a_l_u_e_:

     The number of degrees of freedom.
