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

     Computes the the reconstructed signal from the ridge when the
     epsilon parameter is set to zero

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

     zeroskeleton(cwtinput, Qinv, morvelets, bridge, aridge, N)

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

cwtinput: continuous wavelet transform (as the output of `cwt'). 

    Qinv: inverse of the reconstruction kernel (2D array). 

morvelets: array of Morlet wavelets located at the ridge samples. 

  bridge: time coordinates of the ridge samples. 

  aridge: scale coordinates of the ridge samples. 

       N: size of reconstructed signal. 

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

     The details of this reconstruction are the same as for the
     function skeleton. They can be found in the text

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

     Returns a list of the elements of the reconstruction of a signal
     from sample points of a ridge 

     sol: reconstruction from a ridge.

       A: matrix of the inner products.

     lam: coefficients of dual wavelets in reconstructed signal. They
          are the Lagrange multipliers lambda's of the text.

dualwave: array containing the dual wavelets.

_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:

     `skeleton', `skeleton2', `zeroskeleton2'.
