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

     Compute the continuous wavelet transform with (complex-valued)
     Cauchy's wavelet.

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

     cwtTh(input, noctave, nvoice=1, moments, twoD=TRUE, plot=TRUE)

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

   input: input signal (possibly complex-valued). 

 noctave: number of powers of 2 for the scale variable. 

  nvoice: number of scales in each octave (i.e. between two consecutive
          powers of 2). 

 moments: number of vanishing moments. 

    twoD: logical variable set to `T' to organize the output as a 2D
          array (signal size x nb scales), otherwise, the output is a
          3D array (signal size x noctave x nvoice). 

    plot: if set to `T', display the modulus of the continuous wavelet
          transform on the graphic device. 

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

     The output contains the (complex) values of the wavelet transform
     of the input signal.  The format of the output can be

     2D array (signal size x nb scales)

     3D array (signal size x noctave x nvoice)

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

     tmp: continuous (complex) wavelet transform.

_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:

     `cwt', `cwtp', `DOG', `gabor'.
