使用AbstractTableModel构建Table在表格中添加JButton按钮，之前在网上找了2天没有找到好用的程序，最终终于找到一个好用的例子。
不要使，我退你们分。

使用emd进行回归预测的代码，使用方法结单，只需输入训练集和测试集就可以进行emd预测了，预测的结果会保存在相应的.mat文件里，详细操作请看代码里的操作说明。
资源里有demo，guidence.m文件里有调用实例，直接复制到commandwindows里运行就可以了，简单易懂，汉语注释说明等。
运行结果会直接输出测试集的MAE,RMSE,MAPE,DISTAT这几个统计量

Spy4Win(SpyforWindowXP、Win7)是一个类似MSSpy++的辅助工具，主要功能是探测和获取窗口的更多信息(窗口基本信息，窗口的样式描述以及动态改变窗口样式，识别控件来源，窗口类的相关信息，关系窗口的获取(父窗口/子窗口等)，窗口内容的读取，窗口消息截获，可视窗口截图等)。
提供了多种方法查找窗口(拖拽鼠标/枚举窗口(EnumWindow)/查找窗口(FindWindow)/直接指定窗口句柄/用热键获取当前鼠标下窗口等)；
可以从可执行文件中提取窗体可重用单元并生成Delphi和C++Builder支持的单元文件；
克隆其他程序中的窗体菜单或系统菜单并应用到Delphi和C++Builder中；
IE页面分析功能包括读取IE页面元素，缩放页面，高亮页面中的关键字，提取所有链接/图片链接/Flash链接，运行JavaScript和VBScript脚本等；
程序代码生成可直接生成查找窗口和读取/设置窗口样式的代码以及窗口样式描述的参考，目前支持C++/Delphi/VB；
屏幕颜色拾取获取屏幕任何一点的颜色并可将其储存起来，一组支持6个颜色，还兼有放大镜功能；
进程管理包括当前进程/模块/线程查看；
软件界面可根据用户的爱好自定义主题色彩，新版本中提供了对插件的支持，可以通过编写Dll来扩充软件功能

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
