Matlab -手写数字识别-手写数字识别python,matlab源码有GUI界面代码清晰

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