							function wavedemo(option,in2,in3)
%WAVEDEMO Wavelet Toolbox demos.
%   WAVEDEMO brings up a GUI that allows you to choose
%   between several Wavelet Toolbox demos.
%   WAVEDEMO('auto') shows all the demos in automatic mode.
%
%   WAVEDEMO('gr_auto') shows all the demos in automatic mode:
%   first in the increasing slide order and then in the 
%   decreasing slide order.
%
%   WAVEDEMO('loop') shows all the demos in loop mode.
