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

     Dyadic wavelet transform, with Mallat's wavelet. The reconstructed
     signal preserves locations and values at extrema.

_U_s_a_g_e:

     mw(inputdata, maxresoln, filtername="Gaussian1", scale=FALSE, plot=TRUE)

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

inputdata: either a text file or an R object containing data. 

maxresoln: number of decomposition scales. 

filtername: name of filter (either Gaussian1 for Mallat and Zhong's
          wavelet or Haar wavelet). 

   scale: when set, the wavelet transform at each scale is plotted 
          with the same scale. 

    plot: indicate if the wavelet transform at each scale will be
          plotted. 

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

     The decomposition goes from resolution 1 to the given maximum
     resolution.

_V_a_l_u_e:

     Structure containing 

original: original signal. 

      Wf: dyadic wavelet transform of signal. 

      Sf: multiresolution of signal. 

maxresoln: number of decomposition scales. 

      np: size of signal. 

_R_e_f_e_r_e_n_c_e_s:

     See discussions in the text of ``Practical Time-Frequency
     Analysis''.

_S_e_e _A_l_s_o:

     `dwinverse', `mrecons', `ext'.
