Matlab 各种电动机的仿真，以及在运行中出现状况是的故障仿真，一共50个(Matlab simulation of various motor, as well as in operation in the condition of fault simulation)

创建一个感知器网络，看前面的网络训练结果图形(Create a sensor network, network training to see the results of the previous graph)

说明：  利用 matlab 分别基于 ACF 和 W-AMDF 求基音频率，程序均调试通过。其中的 word 文档为下载资源，供大家参考对比(compute fundamental frequency of speech signal base on ACF and W-AMDF respectively, while the download word document for your reference.)

整车7自由度无阻尼模态分析，主要是求出整车固有频率和振型，用于后续处理(7 DOF vehicle undamped modal analysis, the vehicle is mainly determined natural frequencies and mode shapes, for subsequent processing)

利用MATLAB开发软件进行编程，实现了数字FIR低通滤波器的功能，程序直接可以运行！(Use MATLAB to develop software for programming, implementation of digital FIR low-pass filter function, the program can run directly!)

粒子群优化最优路径算法，和模拟退火算法相似，它也是从随机解出发，通过迭代寻找最优解，它也是通过适应度来评价解的品质，但它比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优(Similar to simulated annealing (SA), particle swarm optimization (PSO) optimizes the optimal path by iteratively searching for the optimal solution from a random solution. It also evaluates the quality of the solution by fitness, but it is simpler than the genetic algorithm rules. It does not have the crossover and Mutation operations of genetic algorithm. It finds the global optimum by following the best values currently searched.)

说明：  雷达信号处理、雷达检测，波形 ，信噪比，波形检测(Radar signal processing, radar detection, waveform, signal to noise ratio)

Here i attach the MATLAB codings for dsp applications. with the help of these coding we can easily design the dsp applications

This code is for face recognition using PCA
