_h_f._u

_D_e_s_c_r_i_p_t_i_o_n:

     Denoises a Gaussian contaminated vector using wavelet thresholding
     with the universal threshold. Requires WaveThresh3. Also see help
     to 'wd', 'threshold',and 'link{wr}' in WaveThresh.

_U_s_a_g_e:

     hf.u(x, filter.number = 10, family = "DaubLeAsymm", min.level = 3, type = "hard")

_A_r_g_u_m_e_n_t_s:

       x: The noisy vector, its length must be a power of 2.

filter.number: The filter number of the analysing wavelet. Can be set
          to 1, 2, ..., 10 for 'family == "DaubExPhase"', or to 4, 5,
          ..., 10 for 'family == "DaubLeAsymm"'.

  family: The family of wavelet bases from which the wavelet
          'filter.number' is chosen. Can be set to "DaubExPhase" or
          "DaubLeAsymm".

min.level: The minimum level thresholded.

    type: Type of thresholding, can be set to hard or soft

_V_a_l_u_e:

     Returns:  

     est: Denoised version of 'x'.
