差分检测的程序，包括一个调制程序，以及两个检测程序：一个是比较复杂但是易于理解的，一个是简便方法。对于理解调制解调的初学者来说，很有帮助(Differential detection procedures, including a modulation process, as well as two testing procedures: one is more complicated but easy-to-understand, one is the easy way. For understanding the modulation and demodulation for beginners, very helpful)

k均值算法是一种迭代求解的聚类分析算法，其步骤是随机选取K个对象作为初始的聚类中心，然后计算每个对象与各个种子聚类中心之间的距离，把每个对象分配给距离它最近的聚类中心。聚类中心以及分配给它们的对象就代表一个聚类。(kmeans algorithm is an iterative solution clustering analysis algorithm. First, the initial clustering centers are randomly selected. Then, distance between between each point ans others are calculated, and each data point is designed to its nearest clustering center.)

利用Matlab软件方便的从海量文件夹里找出你想要的文件，使你不必做一些重复性的劳动(Using Matlab software easy to find from a massive folder of files you want, so you do not have to do some repetitive work)

Data Acquisition数据获取代码，主要从麦克风获取语音信号，然后real time plot输入信号的时域和频域波形图(Data Acquisition Data acquisition code, mainly for voice signal from the microphone, and then real time plot of the input signal in time domain and frequency domain waveform)

Matlab作业，Matlab的基础应用，包括矩阵操作，微积分数值及符号求解，Matlab编程(Activity-based applications Matlab)

利用粒子群算法对支持向量机（SVM）进行分类优化(optimizate the support vector machine (SVM) classification )

QR factorization of an m × n matrix A with m ≥ n is a pair of matrices A = QR

几个利用uicontrol进行gui编程的matlab脚本文件：生成菜单修改fig颜色，绘制正弦并允许字体调整，归一化二阶系统的阶跃响应(use gui programming for the Matlab script file : Generation fig menu changes color rendering fonts sinusoidal and allow adjustments to a second-order system of the step response)

读取Yokogawa DL 750, DL 1600 系列 与 DL 7440 示波器的数据. 特点：允许多个通道（trace）的输入，如： [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) (loads YT-waveform data from*.wvf file saved by Yokogawa DL 750, DL 1600 series and DL 7440 Oscilloscopes into the variables y (y data) and t (time data). The matrices ind_over and ind_under, illegal contain the indices of overranged data points outside the upper/lower limit of the TDS AD converter and indices of illegal values. advantage：permit several traces, e.g. [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) )
