一种下垂控制的模型，参数设好，可以运行，仅供参考学习。( One kind of droop control model, the parameters had set up, you can run it,just for reference study.)

学习盲源分离的独立分量分离，可以作为学习盲源分离的基本程序(Learning blind source separation independent component can be used as learning the basic procedures for blind source separation)

说明：  QC-LDPC的主程序，IEEE802.16e标准，考察迭代次数对误码率的影响(Various encoding and decoding methods of LDPC)

层次分析法实现，从几个决策中选择最佳决策，得到判断矩阵(Analytic Hierarchy Process to achieve, choose the best decision several decisions, obtain judgment matrix)

机床主轴回转精度模拟，可以求其回转精度，圆度误差等(Spindle rotation accuracy simulation, you can find its rotary precision, roundness error, etc.)

本代码可不用借助其他工具直接对光子晶体光纤的色散等直接计算，对学习pcf的朋友很有帮助！(This code can be without the help of other tools directly on the photonic crystal fiber dispersion and other direct calculation, learning pcf helpful friends!)
