matlab 0~9GUI手写模式识别，正确率挺高的

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