说明：  学习MATLAB中的关系运算和逻辑运算，掌握它们的表达形式和用法。掌握MATLAB 中的选择结构和循环结构。学会用MATLAB进行M文件的编写和调用。 (Learning MATLAB relational and logical operations, control their expression in the form and usage. Master MATLAB selection structure and loop structure. Learn to write and call the M-file with MATLAB.)

matlab很强大应用——pca的应用，希望对你有用，很好，很强大(Matlab is strong applications-the application of pca, hope to be useful to you, very good, very strong)

解决图论中最短路问题的最好方法--“Dijstra算法,”通过解析实例模型,对模型算法进行描述、拓展,并给出了求最短路以及求最短路长的MATLAB程序,此程序具有通用性。(The best way to solve the shortest path problem in graph theory is- "Dijstra algorithm," by parsing instance model, the model describes the algorithm, expand, and gives the shortest and seek seek the shortest length of the MATLAB program, this program has versatility.)

说明：  这是用MATLAB写的一个RD算法的程序，不知道有人上传过没有，希望有用(This is used to write a MATLAB algorithm RD procedure, I do not know it was not uploaded, I hope useful)

说明：  这个程序对于学习流行学习算法的朋友很有借鉴意义，在matlab上能够运行。(This procedure popular learning algorithm for learning a friend of referential significance, in the matlab able to run.)

通信原理课程设计利用matlab中的simlingk做的伪随机码的设计(Communication Theory course design using matlab in simlingk do pseudo-random code design)

说明：  MMC中IGBT损耗计算与结温模块（计算开关周期内的损耗，公式可以参考 电工技术学报 WXP先生 2018-12-14 的一篇文献），还有一对VT+VD的Foster。公式及其实现没有问题，仿真过程可能出现代数环，如果有自己的Foster或者Cauer最好。(power loss calculation&junction temperature detection of IGBT in MMC)

说明：  人脸识别PCA方法特征脸的建立与人脸重建(PCA method for face recognition features of the establishment and face reconstruction)

信号的短时傅立叶变换，paper2_2_1为主程序，仿真不同窗长下短时傅立叶变换的时频聚集度。stftxz为修正的短时傅立叶变换。(Short-time Fourier transform signals, paper2_2_1 main program, the simulation under different window length short time Fourier transform of the frequency of aggregation. stftxz to correct short-time Fourier transform.)
