手写字母或数字的简单距离对比识别GUI（matlab实现）

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