一、简介
如今，果农为了保证水果销售利益最优化，会根据水果品相、大小分为不同等级，以此进行包装出售。传统的人工以目测检测为主，效率较为低下，人为误测大，不能够很好地评价水果质量。
该博客基于matalb GUI界面的水果分级系统，该系统适用范围以圆形水果为准，比如橘子，龙眼等，以统计水果的直径、色泽等多参数进行评价。该系统带一个GUI界面，通过设置直径与色泽，测试水果的这些参数，从而得出该水果所属的等级。
二、源代码
function varargout = myself(varargin)
% MYSELF MATLAB code for myself.fig
% MYSELF, by itself, creates a new MYSELF or raises the existing
% singleton*.
%
% H = MYSELF returns the handle to a new MYSELF or the handle to
% the existing singleton*.
%
% MYSELF('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MYSELF.M with the given input arguments.
%
% MYSELF('Property','Value',...) creates a new MYSELF or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before myself_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to myself_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
