%Note:Three .mat files of names path.mat,value.mat and

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