%DEMOGUIWAITBAR M-file for demoGUIWaitbar.fig
%      DEMOGUIWAITBAR, by itself, creates a new DEMOGUIWAITBAR or raises the existing
%      singleton*.
%
%      H = DEMOGUIWAITBAR returns the handle to a new DEMOGUIWAITBAR or the handle to
%      the existing singleton*.
%
%      DEMOGUIWAITBAR('Property','Value',...) creates a new DEMOGUIWAITBAR using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to demoGUIWaitbar_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      DEMOGUIWAITBAR('CALLBACK') and DEMOGUIWAITBAR('CALLBACK',hObject,...) call the
%      local function named CALLBACK in DEMOGUIWAITBAR.M with the given input
%      arguments.
