聚类工具箱，此工具箱在处理聚类问题时，作用很大！(FCM toolbox)

内含巴特沃思滤波器（Butterworth）MATLAB代码，分高通与低通两种情况，并用mesh显示滤波器的三维图(Containing Butterworth filter (Butterworth) MATLAB code, sub-high-pass and low pass both cases, with mesh filter of three-dimensional map display)

一些关于谱分析的matlab程序，和朋友们一起分享，希望能共同交流！(Spectral analysis on the matlab program, and friends to share, hoping to share!)

说明：  该代码用遗传算法来优化多函数极值问题，可以很方便的解决非线性方程的极值(The code using a genetic algorithm to optimize multi-function extremum problem can easily solve nonlinear equations extremum)

levy飞行改进pso,更好的pso改进措施，大家可以看看(levy_Flight to improve pso)

沈辉编著的《精通simulink系统仿真与控制》一书的例题仿真，我自己做的，大家有需要可以借鉴。(Shen Hui edited " Mastering simulink simulation and control system," a book example simulation, I do, we need to be able to learn from.)

说明：  用双线性变换法设计一个Butterworth低通滤波器，要求其通带截止频率100Hz，阻带截止频率200Hz，通带衰减小于2dB，阻带衰减大于15 dB，采样频率为500 Hz。(Using bilinear transformation to design a Butterworth low-pass filter, requiring that their pass-band cutoff frequency 100Hz, stopband cutoff frequency 200Hz, pass-band attenuation is less than 2dB, stop-band attenuation greater than 15 dB, a sampling frequency of 500 Hz.)
