用FDTD方法仿真共面波导弯角，S参数分奇偶模。(using FDTD method to simulate coplanar waveguide bend.)

第17章 数据统计和分析.zip。是从书中光盘里直接拷贝的代码，放在这里，与大家共享，共同交流，希望对大家有帮助。(Chapter 17 Statistics and analysis.zip)

利用MATLAB来实现离散傅里叶变换和离散傅里叶逆变换，N为离散傅里叶变换长度，形式为xk=IDFT（xn，N）(To achieve the discrete Fu Liye transform and discrete Fu Liye transform by using MATLAB, N as the discrete Fu Liye transform length, form xk=IDFT (xn, N))

Windows in matlab. Blackmanharris, Hamming, Gauss, Kaiser. There is tool for comparing different windows with different parameters. Parameter N set the window length

enfrmae函数,可以用于对语音信号进行处理前的分帧(enfrmae function can be used to process the speech signal prior to framing)

It is book for communication engineering. It will help the students.

基于CVA+som的故障诊断,0为simple SOM，1为PCA+SOM, 2为CCA+SOM(CCA与PLS算法相同),3为LDA+SOM, (Based on CVA+ som fault diagnosis, 0 for the simple SOM, 1 for the PCA+ SOM, 2 for the CCA+ SOM (CCA and PLS algorithm the same), 3 for the LDA+ SOM,)

本书全面系统地介绍了遗传算法的基本理论，重点介绍了遗传算法的经典应用和国内外的新发展。(Genetic Algorithm，GA)
