本文件是一个SPWM逆变器的仿真源文件，可以在MATLAB7.1中直接运行。设计中PWM Generator采用外部调制信号，并在调制信号中注入了三次谐波，很好的抑制了输出谐波，同时提高了直流电源的利用率。(This document is a SPWM inverter simulation source file, you can directly run MATLAB7.1. Design of PWM Generator external modulation signal, and in the modulation signal into the third harmonic, the output of good harmonic suppression, while improving the utilization of the DC power supply.)

this is both histogram and otsu code

说明：  扩展卡尔曼滤波 用于信号处理, 初学者可是直接仿真使用(Extended kalman filter for signal processing, beginners but direct simulation use)

基于简单一元函数的遗传算法，通过使用Shdffield工具箱，更好的实现了遗传算法的每一步，并将其结果以图的形式展现出来。代码清晰易懂。(Functions of one variable based on a simple genetic algorithm, by using Shdffield toolbox to achieve better every step of the genetic algorithm, and the results show up in the form of graphs. Code is clear and understandable.)

说明：  基于基追踪的重构图像实验，易于实现，也有相应的助手(Based on the reconstructed image based tracking experiment, easy to implement, but also the corresponding assistant)

Matlab code for sphit code and its use in compresion details

1、系统仅处于训练状态。训练序列为2cos(2π×f1×n/fs)， 干扰为sin(2π×f2×n/fs)；序列长度为100个样点。 其中n=0…99，f1=1kHz，f2=2kHz，fs=8kHz。 2、采用LMS算法，均衡器输入为训练序列加上干扰，均衡器阶数为21阶，步长因子β=0.01。 3、在Matlab中编写浮点LMS算法，绘制均衡器的输出波形，并与训练序列进行对比。 (1, the system only in the training status. The training sequence is 2cos (2πf1n/fs), interference sin (2πf2n/fs) sequence length of 100 samples. Where n = 0 ... 99, f1 = 1kHz, f2 = 2kHz, fs = 8kHz. 2, using LMS algorithm, the input to the equalizer training sequence plus interference equalizer order is 21 bands, step factor β = 0.01. 3, the preparation of the floating-point LMS algorithm in Matlab, draw the output waveform equalizer, and with the training sequence comparison.)
