在加噪声的情况下，利用pso（粒子群算法）辨识NARMAX模型(实例一）(In the case of additive noise, the use of pso (PSO) identify NARMAX model (Example I))

说明：  这是一个对已知数据的描点的matlab代码，对刚接触matlab软件的学者比较具有参考价值(The description on the known data points)

实现信号LMS处理，并输出波形，能够实现信号的处理，可用于声音的处理(It can realize signal LMS processing and output waveform. It can realize signal processing and can be used for sound processing.)

一个ram例子，可以参考一下，希望能帮到你，请用winrar解压缩打开。(A ram example, you can refer to, I hope you can help, please use winrar to decompress opened.)

本代码主要提供了在频域使用fastica进行盲源分离，并且解决了频域的排列和增益两个歧义性问题。(This code mainly provides the use of fastica in the frequency domain for blind source separation, and solves the frequency domain arrangement and gain of two ambiguity problems.)

用照度分割法设计路灯花生米透镜，具体思路参照 张奇辉大功率LED照明系统光学设计方法研究 第四章 （非原创）(The method of illumination segmentation is used to design the peanut lens of street lamp. The concrete idea is referred to the fourth chapter of the optical design method of Zhang Qihui high power LED lighting system (not original))
