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

     Reconstruct from dyadic wavelet transform modulus extrema. The
     reconstructed signal preserves locations and values at extrema.

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

     mrecons(extrema, filtername="Gaussian1", readflag=TRUE)

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

 extrema: the extrema representation.  

filtername: filter used for dyadic wavelet transform. 

readflag: if set to T, read reconstruction kernel from precomputed
          file. 

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

     The reconstruction involves only the wavelet coefficients, without
     taking care of the coarse scale component. The latter may be added
     a posteriori.

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

     Structure containing 

       f: the reconstructed signal. 

       g: reconstructed signal plus mean of original signal. 

       h: reconstructed signal plus coarse scale component of original
          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:

     `mw', `ext'.
