给出一种用MATLAB实现信号频谱分析和显示的快速傅里叶算法的方法(FFT)

em算法的matlab实现，简单适合入门，可以参考(em algorithm matlab implementation, simple for entry, refer to)

种群选择，自然选择，提供了基础的遗传算法程序。相信一定会对初学者有很好的学习效用。(Species selection, natural selection provides the basis for the genetic algorithm program. Believe that we will have a good beginners learning effectiveness.)

这是篇关于左手材料的PPT，比较简单，适合于刚入门的人(This the chapter on the left hand material PPT, relatively simple and suitable for people who just look at the portal)

本文件仿真有关LCL滤波器的伯德图，希望大家一起学习。仿真并不是很全面，没有把所有的情况都考虑在内，但是提供了一个仿真的思路。(This document the simulation about the bode plots of the LCL filter, hope we learn together. Simulation is not very comprehensive, not all things into consideration, but provides a simulation of train of thought. )
