kmeansK
KMEANSK Performs K-means clustering given a list of feature vectors and k
The argument k indicates the number of clusters you want the data to be
divided into. data_vecs (N*R) is the set of R dimensional feature
vectors for N data points. Each row in data_vecs gives the R
dimensional vector for a single data point. Each column in data_vecs
refers to values for a particular feature vector for all the N data
points. The output data_idxs is a N*1 vector of integers telling which
cluster number a particular data point belongs to. It also outputs
centroids which is a k*R matrix, where each rows gives the vector for
the cluster center. If we want to segment a color image i into 5
clusters using spacial and color information, we can use this function
as follows:

2ASK
说明: 不用matlab里面的函数,自己写出来的2ASK的仿真程序,加入了白噪声,经过滤波后的波形有些变形,可能是滤波器的原因。仅供参考。(inside Matlab not a function of their 2ASK written by the simulation program, joined the white noise, filtered waveforms after some deformation, the filter may be reasons. For reference purposes only.)

Method-for-solving-EM-problems
提出了一种求解电磁场有限元 边界元混合法所生成的线性方程组的有效方法 ———内观
法结合多波前法.由于该线性方程组的系数是一个部分稀疏部分满填充的矩阵,为了加速求解,应用内观法将系数矩阵分为 2块,一块是有限元法形成的稀疏矩阵,另一块是边界元法生成的满阵,然后用多波前法求解稀疏矩阵方程,用高斯 约当消去法解满阵方程. 采用该方法,计算了二维多层介质柱体的雷达散射截面.计算结果表明,该方法的计算效率远远高于传统的高斯法.(Proposed for solving mixed finite element boundary element linear equations generated by an effective method of Vipassana--- a combination of multi wave front method. Since the coefficients of linear equations is a part of the sparsely populated part of the full matrix, in order to speed up the solution, application of Vipassana coefficient matrix is divided into two, one is the finite element method for the formation of the sparse matrix, the other is the boundary element method generates the full array, and then use the multifrontal method for solving sparse matrix equation Gauss Jordan elimination method with full matrix equation solution. use this method to calculate the two-dimensional multi-layer dielectric cylinder of the radar cross section. The results show the computational efficiency of this method is much higher than the traditional Gaussian law.)

数字信号处理MATLAB
120多个用MATLAB编写的信号处理程序,它们是本书各个章节的大部分例题。用MATLAB编写的程序的名称由“exa”开头,接下来是所在的章、节及例题的序号,如exa010101,指的是第1章第1节(即1.1节)的第1个例题,即例1.1.1。如果该程序是为了说明某一个m文件的应用,则在上述名称的后面跟一个下划线,再在后面加上所说明的MATLAB文件的名称,如exa011001_rand,即是例1.10.1,该例用来说明rand.m文件的应用。(More than 120 signal processing programs written in MATLAB are most of the examples in each chapter of this book. The name of the program written in MATLAB begins with "exa", followed by the ordinal number of the chapters, sections and examples, such as exa0101, which refers to the first example of chapter 1, section 1 (i.e. section 1.1), namely example 1.1.1. If the program is to illustrate the application of an M file, then follow the above name with an underscore, and then add the name of the MATLAB file, such as exa011001_rand, which is Example 1.10.1. This example is used to illustrate the application of rand.m file.)
