function varargout = f_8_13(varargin)
% F_8_13 MATLAB code for f_8_13.fig
%      F_8_13, by itself, creates a new F_8_13 or raises the existing
%      singleton*.
%
%      H = F_8_13 returns the handle to a new F_8_13 or the handle to
%      the existing singleton*.
%
%      F_8_13('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in F_8_13.M with the given input arguments.
%
%      F_8_13('Property','Value',...) creates a new F_8_13 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before f_8_13_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to f_8_13_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
