【手写数字识别】基于Fisher分类实现手写数字识别附matlab代码

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