BouncingBall

实现基本的PCM编译码功能，函数简单，程序可行(PCM encoding and decoding functions to achieve the basic function is simple, practical procedures)

this is the matlab code for pcm "pulse code modulation"

FDTD（时域有限差分法）算法的Matlab源程序(FDTD (FDTD) algorithm Matlab source code)

matlab IIR带通 滤波器设计 m文件 巴特沃斯，车比雪夫I，车比雪夫II,椭圆(matlab IIR band-pass Butterworth filter design m documents, vehicles Chebyshev I, car Chebyshev II, Elliptic)

you can see how the ball is tracking on the short movie

说明：  支持向量机 matlab 源代码 m文件(SVM matlab)

fractional detative eqaution

做DEA用的,功能很强大,大家可以试试看,真的很好用(DEA do use, very powerful, we can try, really well)

RLS均衡器 matlba 代码，对研究现代书记信号处理的朋友有很大帮助(RLS equalizer matlba code, the study of modern signal processing secretary friends are very helpful)

采用L-M优化算法用以训练BP神经网络，使其能够拟合某一附加有白噪声的正弦样本数据。设计一个三层BP神经网络，其网络的隐含层神经元的激励函数为双曲正切型，输出层各神经元的激励函数为线性函数，隐含层有6个神经元(LM optimization algorithm used to train BP neural network to enable it to fit a white noise, sine additional sample data. Design a three BP neural network, its network of hidden layer neuron activation function of hyperbolic tangent type for the output layer activation function of each neuron is a linear function of the hidden layer has 6 neurons)
