使用PID参数模糊自整定，进行非线性系统仿真研究(Fuzzy self-tuning PID parameters of nonlinear system simulation )

This tutorial white-paper illustrates practical aspects of FIR filter design and fixed-point implementation along with the algorithms available in the Filter Design Toolbox and the Signal Processing Toolbox for this purpose. The emphasis is mostly on lowpass filters, but many of the results apply to other filter types as well. The tutorial focuses on practical aspects of filter design and implementation, and on the advantages and disadvantages of the different design algorithms. The theory behind the design algorithms is avoided except when needed to motivate them.

实现线性卷积、圆周卷积、周期卷积的动态演示，以及采样定理，滤波器的设计。(Achieve linear convolution, circular convolution, convolution cycle dynamic presentation, and the sampling theorem, the filter design.)

分水岭分割算法的MATLAB实现，本人测试过很好用(wavelet segmentation MATLAB code )

本程序为粒子算法找最小值，很有启发意义，大家可以借鉴下(This program is to find the minimum particle algorithm, very instructive, we can learn from the next)

应用sift算子进行图像匹配，效果不错。。。(sift is used to match two picture，the result is good...)

Implemenation of a variant of the rotation forest (Rodriguez et al., Rotation Forest: a new classifier ensemble method, PAMI 2006) proposed in L. Nanni and A. Lumini, Using ensemble of classifiers in Bioinformatics, in H. Peters and M. Vogel, Machine Learning Research Progress, Nova publisher, 2009

此程序利用强化学习的方法实现小车的最优控制。(Optimal control of car)

说明：  按照要求改变平面加速度、速度，作出路径，显示加速度、速度、位移随时间变化(Change the acceleration and speed in a plane according to the requirement, and draw the path.)

最小模法估计DOA,并求出估计角，这是一种传统的DOA估计方法。(Minimum norm method to estimate the DOA, and find the estimated angle, which is a traditional method of DOA estimation.)
