matlab6.5下写的三类问题的基于最大最小聚类方面写的聚类程序(matlab6.5 wrote under the three categories based on the largest area was the smallest cluster clustering procedure)

这是一个用matlab编写的，基于CAMC，pid神经网络的非线性系统识别程序，能够很好的识别非线性系统(Based on CAMC/PID Nonlinear System Identification)

LFM信号的分数傅里叶变换分析，包含LFM信号分数阶谱图产生及FrFt子程序，及峰值搜索。非常好用。(LFM signal' s fractional Fourier transform, including the LFM signal generation and FrFt fractional spectrum of subroutines, and peak search. Very easy to use.)

实现在matlab环境下的直线检测，效果很好(Straight line detection, with good results achieved in the matlab environment)

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.)

matlab与C的混合编程,非常实用,大家可以载下(matlab and C comibine program，it is very useful)

经典的利用matlab做的卡尔曼滤波。代码可以运行。读者可以和PF对比；(Classic Kalman filter using matlab to do. Code can run. Readers can compare and PF )

说明：  简单的实现了weiner滤波的功能，可以用于信号处理，可以用(Simple implementation of the weiner filtering function can be used for signal processing)

this is equalizer mat lab code used in digital systems. the code has detailed description of equalizer matlab code
