这是一个比较好的基于主元分析PCA的代码，个人觉得很有价值。...

3D显示一个DEMO程序,仅供参考-3D display a DEMO procedures for reference

判断点是否属于一个多边形。最基本的功能，但很实用，从中可以学到一些很基本的几何操作，非常适合初学者啊啊啊啊啊。非商业用途，请尊重别人的知识产权。

功能和界面全部模仿于Windows自带的画图板，界面如截图。功能主要有： 手绘线、简单图形、文字输入、图块拖放、重复撤销、画面缩放、打开保存图片文件，另外为了直接从数据库或者XML中存取图片，另外还提供了从Base64编码存取图片的接口，其他还实现了和画图板同样效果的工具箱及颜料盒。 -Features and interfaces in Windows, bringing all to imitate the drawing board, interface, such as screenshots. The main features include: hand-drawn lines, simple graphics, text input, drag and drop block, repeated withdrawal, screen zoom, open the saved image file, and directly from the database in order to access images or XML, in addition to the provision of deposit from the Base64 encoding picture of the interface from the other have also achieved the same effect and drawing board of the toolbox and the color cartridge.
