计算以为二维三维情况下波导的FDTD程序 为MATLAB格式 对初学者很有帮助(Calculations to 2D and 3D FDTD waveguide case procedures Very helpful for beginners to MATLAB format )

分数付利叶变换的第二种算法 matlab程序(The m-file frft2.m computes the fast fractional Fourier transform following the algorithm)

PLS-DA法是将定量偏最小二乘法用于判别分析的一种策略，其基本思想是将已知类别样本的浓度阵分别设为0、1（对两类用PLS1方法而言），或-1、0、1（对三类用PLS1方法而言），或01、10（对两类用PLS2方法而言），或001、010、100（对三类用PLS2方法而言），多类问题依次类推，再通过定量PLS方法建立模型。(PLS- DA method is to use quantitative partial least squares discriminant analysis of a kind of strategy, the basic idea is to known categories the concentration of the sample matrix is set to 0, 1 (for two types of PLS1 method), or 1, 0, 1 (for three types of PLS1 method), or 01, 10 (for two types of PLS2 method), or 001, 010, 100 (for three PLS2 method), many questions so on, through quantitative PLS method to establish model.)

本文详细介绍了最大独立集的频谱分配算法，如果不考虑认知用户之间的干扰关系以及频谱的效益，本文值得读者借鉴(This paper describes the spectrum allocation algorithm for maximum independent set, if you do not consider the relationship between cognitive interference between users and spectrum efficiency, this article is worth the reader learn)
