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

     Computes the maxima (for each fixed value of the time variable) of
     the modulus of a continuous wavelet transform.

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

     tfgmax(input, plot=TRUE)

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

   input: wavelet transform (as the output of the function `cwt') 

    plot: if set to TRUE, displays the values of the energy as a
          function of the scale. 

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

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

  output: values of the maxima (1D array)

     pos: positions of the maxima (1D array)

_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:

     `tflmax'.
