% GUI_I_14_6 M-file for gui_I_14_6.fig
% GUI_I_14_6, by itself, creates a new GUI_I_14_6 or raises the existing
% singleton*.
%
% H = GUI_I_14_6 returns the handle to a new GUI_I_14_6 or the handle to
% the existing singleton*.
%
% GUI_I_14_6('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in GUI_I_14_6.M with the given input arguments.
%
% GUI_I_14_6('Property','Value',...) creates a new GUI_I_14_6 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before gui_I_14_6_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to gui_I_14_6_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
