% exe0.m is a function used to get the six basic initial parameters from the graphical 
%        user interface (aset_win_f).


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 0. THE USER CAN SPECIFY THE FOLLOWING SIX PARAMETERS USING THE GUI      %
%
%      numf == number of formants ( 5,4,flexible)
%      vt == vocal tract model (lpc, formant)
%      sr == excitation source model (polynomial, LF)
%      Order == the order for LP analysis (13,12,11,10,14)
%      fram_len == the length of the LP analysis frame (250,100,128,150,200,300,350)
%      over_len == the length (amount) of frame overlap (50,20,40,60,80,100)
        
% basic=[numf vt sr Order fram_len over_len m_len]
