哨兵-2号数据处理教程，采用dos命令处理，包括大气校正、重采样等(Sentinel-2 data processing tutorial, using DOS command processing, including atmospheric correction, resamping, etc)

箱体趋势突破EA，破解版本。(Box trend break through EA, break the version.)

EGO算法是基于kriging模型的全局优化方法，不通过函数而是通过样本模型寻优，文件给出实例，加载相应的工具箱即可。(EGO algorithm is a global optimization method based on Kriging model. Instead of function, it is optimized by sample model. The example is given in file, and the corresponding toolbox can be loaded.)

端面抽运Yb石英光纤激光器理论计算，matlab程序(end pumping of Yb doped fiber lasers)

选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)
