要求包含如下功能：
1、可创建不少于100名学生成员；
2、每名成员的记录包括：学号、姓名、专业和5门课程的成绩；
3、能够实现添加、删除、修改学生成员；（增加非法字符警告）
4、能够实现添加、删除、修改学生成员的课程成绩；（增加非法字符警告）
5、分别计算每一门课程的平均成绩；
6、每一门课程单独排序，输出由高到低的课程、姓名、成绩信息。
7、提供图形界面实现上述功能，界面包含
（1）系统登录界面
（2）添加、删除、修改界面
（3）被选中学生信息显示界面(基本信息，课程成绩，平均成绩)
（4）被选中课程信息显示界面(排序后的课程成绩，学生基本信息)
第一次弄gui，借鉴别人的代码（手动狗头）
参考博客MATLAB GUI图形界面设计一个学生管理系统
他已经讲的很好了，所以我就不献丑了（卑微的渣渣就是我）
登录界面我就不附源码啦，毕竟一样一样的
源代码如下（功能界面）
我运行出来是没有问题的，如果出现问题就百度吧，写得有点low，别骂，骂就是you can you up
function varargout = untitled3(varargin)
% UNTITLED3 MATLAB code for untitled3.fig
% UNTITLED3, by itself, creates a new UNTITLED3 or raises the existing
% singleton*.
%
% H = UNTITLED3 returns the handle to a new UNTITLED3 or the handle to
% the existing singleton*.
%
% UNTITLED3('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED3.M with the given input arguments.
%
% UNTITLED3('Property','Value',...) creates a new UNTITLED3 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled3_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled3_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
