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.)

模式识别分类器的设计，此为fisher法源码，经调试通过。所用数据为标准IRIS。(Pattern recognition classifier design, the source for the fisher law, adopted by the debugger. Data used as the standard IRIS.)

The source code is the best neighboring matching method, which will find out a best 16x16 macro block to conceal the lost macor block. this code is written by Matlab.

这是B样条和hermite曲线用MATLAB实现的程序(This is the B-splines and hermite curves achieved using MATLAB program)

逻辑航迹起始算法代码，实现简单的逻辑算法(logical algorithm for Track initiation)

说明：  分布式发电技术的潮流计算，将分布式电源视为PQ与PV节点，再代入配电网络，进行简化计算(The trend of distributed generation computing technology, distributed power regarded as PQ and PV node, and then substituted into the distribution network for simplified calculation)

低通滤波器，每句程序都有注释，易懂，还有一个实例，便于加深认识(Low-pass filter, each sentence programs have notes, easy to understand, there is an instance, to facilitate a better understanding of)
