% PREFERENCES_GUIDE MATLAB code for Preferences_GUIDE.fig
%      PREFERENCES_GUIDE, by itself, creates a new PREFERENCES_GUIDE or raises the existing
%      singleton*.
%
%      H = PREFERENCES_GUIDE returns the handle to a new PREFERENCES_GUIDE or the handle to
%      the existing singleton*.
%
%      PREFERENCES_GUIDE('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in PREFERENCES_GUIDE.M with the given input arguments.
%
%      PREFERENCES_GUIDE('Property','Value',...) creates a new PREFERENCES_GUIDE or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Preferences_GUIDE_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Preferences_GUIDE_OpeningFcn via varargin.
