Difference method of MATLAB

a trial version of PCA and Knn to face recognition. This file is not a full version of a code knn, however it is a good approach to start one.

求解雷诺方程有有限元法、有限差分法、有限体积法，本程序就是采用有限体积法对雷诺方程进行求解。(Solving Reynolds equation has finite element method, finite difference method, finite volume method, the program is the use of finite volume method to solve the Reynolds equation.)

说明：  带三相负载的光伏、电池、风机交流并网系统， 结果不错。 可以参考。(AC grid-connected system of photovoltaic, battery and fan with three-phase load)

用AR谱估计法，welch法，周期图法等计算信号的功率谱，welch法是周期图法的改进。PSD直接从信号本身估计出来。最简单的就是periodogram（周期图法），一种改进的周期图法是Welch"smethod。更现代的一种方法是multitaper method（多椎体法）。Yule-Walker autoregressive (AR) method和Burg method 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
