K近邻算法在Matlab中的实现，相当完整，对研究KNN算法有一定帮助(K nearest neighbor in the Matlab, implementation, rather complete, the study of KNN algorithm has certainly helped)

Dielectric waveguides. Outstanding handbook in electrooptics. Examples of different methods for analysis of modes of dielectric waveguides .Matlab codes are included.

说明：  内附几十种小程序，有状态机、比较器、波形发生器、乘法器、加法器、步进电机控制器等，希望大家能用的上。(Containing dozens of small programs, for reference，This is about FPGA,a tool ,we can study,but in ourselves.)

这是matlab的一些程序希望对大家有用，谢谢了(This is some of the procedures of the matlab hope that useful, thank you)

属于贪婪算法中正交匹配追踪算法，用于信道估计预编码中，利用稀疏性，减小信道估计和反馈的开销，此算法的输出为所需要的系数矩阵，压缩包中还有一些说明(Belonging greedy algorithm orthogonal matching pursuit algorithm, used for channel estimation pre-encoding, the use of sparsity, channel estimation and feedback to reduce the overhead, the output of this algorithm is required for the coefficient matrix, the compressed package and some instructions)

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by: • Using Hadamard matrices • Exploiting the symmetry properties of Walsh functions themselves. • The Hadamard matrix is a square array of plus and minus ones, {+1, -1}, whose rows and columns are mutually orthogonal
