现在商业行为中，在水果出厂前都需要进行质量检测，需要将不同等级的水果进行分级包装，以保证商业利益最大化。可是传统方法都是依靠人工进行检测，效率低下，主观成分大，并不能很好客观地评价出货质量，导致工厂损失利益，增加客户投诉，从而造成品牌效率损失，造成隐形的损失。
该课题为基于MATLAB的水果分级系统。适用圆形水果，如苹果，橘子，柚子，柿子等，统计水果图片的面积，圆形度和色泽等多参数进行评价。该设计带一个GUI界面，通过设置直径和色泽，测试水果的这些参数，从而得出该水果所属等级。
function varargout = appletest(varargin)
% APPLETEST MATLAB code for appletest.fig
% APPLETEST, by itself, creates a new APPLETEST or raises the existing
% singleton*.
%
% H = APPLETEST returns the handle to a new APPLETEST or the handle to
% the existing singleton*.
%
% APPLETEST(‘CALLBACK‘,hObject,eventData,handles,...) calls the local
% function named CALLBACK in APPLETEST.M with the given input arguments.
%
% APPLETEST(‘Property‘,‘Value‘,...) creates a new APPLETEST or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before appletest_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to appletest_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE‘s Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
