function varargout = gui_dyn_14_3(varargin)
% GUI_DYN_14_3 M-file for gui_dyn_14_3.fig
%      GUI_DYN_14_3, by itself, creates a new GUI_DYN_14_3 or raises the existing
%      singleton*.
%
%      H = GUI_DYN_14_3 returns the handle to a new GUI_DYN_14_3 or the handle to
%      the existing singleton*.
%
%      GUI_DYN_14_3('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI_DYN_14_3.M with the given input arguments.
%
%      GUI_DYN_14_3('Property','Value',...) creates a new GUI_DYN_14_3 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before gui_dyn_14_3_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to gui_dyn_14_3_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
