% PROGRAM_I_6220_M_2182A_G_2400 MATLAB code for Program_I_6220_M_2182a_G_2400.fig
%      PROGRAM_I_6220_M_2182A_G_2400, by itself, creates a new PROGRAM_I_6220_M_2182A_G_2400 or raises the existing
%      singleton*.
%
%      H = PROGRAM_I_6220_M_2182A_G_2400 returns the handle to a new PROGRAM_I_6220_M_2182A_G_2400 or the handle to
%      the existing singleton*.
%
%      PROGRAM_I_6220_M_2182A_G_2400('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in PROGRAM_I_6220_M_2182A_G_2400.M with the given input arguments.
%
%      PROGRAM_I_6220_M_2182A_G_2400('Property','Value',...) creates a new PROGRAM_I_6220_M_2182A_G_2400 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Program_I_6220_M_2182a_G_2400_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Program_I_6220_M_2182a_G_2400_OpeningFcn via varargin.

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
