使用matlab实现的很好用的，正确的直方图均衡化代码， matlab编写的(Using matlab to achieve good use, right histogram equalization code, matlab prepared)

SPWM with matlab/simulink!!

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

K近邻分类的Matlab算法，简单，适合初学，验证可用(KNN )

信源编码,香农编码，实现了部分功能。希望大家积极改正。(Source coding, Shannon coding, to achieve some functionality. I hope you actively corrected.)

说明：  阈值基于matlab分析 程序经过实际操作研究 效果较好 非常合适(Very suitable threshold analysis program based on matlab after the actual operation better)

说明：  一个很好地matlab学习课件。是很好地入门资料，讲解深入浅出。( a good learning courseware about Matlab.)

以上是matlab语言环境中的最小二乘法程序(These are the matlab language environment in the least squares procedure)
