function varargout = gui_sigout(varargin)
% GUI_SIGOUT M-file for gui_sigout.fig
%      GUI_SIGOUT, by itself, creates a new GUI_SIGOUT or raises the existing
%      singleton*.
%
%      H = GUI_SIGOUT returns the handle to a new GUI_SIGOUT or the handle to
%      the existing singleton*.
%
%      GUI_SIGOUT('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI_SIGOUT.M with the given input arguments.
%
%      GUI_SIGOUT('Property','Value',...) creates a new GUI_SIGOUT or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before gui_sigout_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to gui_sigout_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
