说明：  蚁群算法的一个代码，大家可以看一下。在主界面直接输入ACATSP就可以了。我跑过了，大家看一下(Ant colony algorithm of a code, we can look at. In the main interface directly ACATSP it. I ran, and we look)

三相桥式整流电路带阻感负载谐波电流源,用simulink搭建的谐波检测仿真电路。用于对所产生的现象进行合理解释，并对波形进行傅立叶频谱分析。(Three-phase bridge rectifier circuit with resistive inductive load harmonic current sources of harmonic detection using simulink simulation circuit structures. Generated for a reasonable explanation of the phenomenon, and the waveform Fourier spectral analysis.)

对二元序列10110010，画出2FSK的波形，其中载波频为码元速率的2倍。(For binary sequence 10110010, draw waveform 2FSK, where the carrier frequency of 2 times the symbol rate.)

ROOT-MUSIC的matlab仿真源码，基于求根方式的music算法，避免了谱峰搜索，优化了计算复杂度(ROOT-MUSIC for matlab simulation source code, algorithm-based Roots music the way to avoid the peak search, optimization of the computational complexity)

说明：  图像处理的分割，很经典的MATLAB 算法，适合做CV分割的初学者(cv )

使用pid方法控制单级倒立摆，解压后把两个文件放在同一个文件夹里双击nn_pid.m就行了(Pid way to control the use of single-stage inverted pendulum, after extracting the two files in one folder double-click on the list nn_pid.m)

学习类书籍，应用数学字典，用于科学家及工程师(Learning books, applied mathematics dictionary for scientists and engineers)

语音识别的MATLAB代码，包括用于测试的语音，实现了利用HMM(隐含马尔可夫)和DTW(动态规划)两种方法的实现。(ASR use HMM and DTW method include wave files use for test and training.)

本代码为自己编写的SAD算法，通过blackcar序列验证了算法的正确性。(I have written the code for SAD algorithm, blackcar sequences show that the algorithm is correct.)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get a certain amount of diversity gain)
