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

     Converts one of the possible outputs of the function `cwt' to
     modulus and phase.

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

     cwtpolar(cwt, threshold=0)

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

     cwt: 3D array containing the values of a continuous wavelet
          transform in the format (signal size x noctave x nvoice) as
          in the output of the function `cwt' with the logical flag
          `twodimension' set to FALSE. 

threshold: value of a level for the absolute value of the modulus below
          which  the value of the argument of the output is set to -pi. 

_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:

     Modulus and Argument of the values of the continuous wavelet
     transform 

 output1: 3D array giving the values (in the same format as the input)
          of the modulus of the input. 

 output2: 3D array giving the values of the argument of the input. 

_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', `DOG', `cwtimage'.
