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

     Given a ridge phi (for the wavelet transform), returns a
     (appropriately) subsampled version with a given subsampling rate.

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

     wRidgeSampling(phi, compr, nvoice)

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

     phi: ridge (1D array). 

   compr: subsampling rate for the ridge. 

  nvoice: number of voices per octave. 

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

     To account for the variable sizes of wavelets, the sampling rate
     of a wavelet ridge is not uniform, and is proportional to the
     scale.

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

     Returns a list containing the discrete values of the ridge. 

    node: time coordinates of the ridge samples.

 phinode: scale coordinates of the ridge samples.

  nbnode: number of nodes of the ridge samples.

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

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

     `RidgeSampling'.
