MATLAB神经网络原理与实例分析， 有大量的关于神经网络的实例，如BP神经网络，rbf神经网络，前馈神经网络等等.(The thesis and example analysis about neural networks. There are many example in this file, for example BP neural networks, neural networks, forward feedback neural network and so on. So, it is valuable to learn the neural networks for beginner. If you have any question, you can keep contact with me by e-mail.)

一个MATLAB版编的 神经网络程序 (MATLAB version of a series of the neural network programming)

说明：  2个程序，MATLAB设计的一个滤波器，将含3个频率分量的信号通过该滤波器，滤除2个高频分量，得到只含低频的信号。 单边带信号调制，用MATLAB实现，是学习信号调制的一个好例子。(Two procedures, MATLAB design a filter, will contain three frequency components of the signal through the filter, filter out high frequency components of two, has been only with low-frequency signal. SSB signal modulation, using MATLAB to achieve, is to study signal modulation of a good example.)

本程序是用于信号滤波的实验程序。 主要功能是进行信号的保相滤波。 对计算滤波信号的幅值问题进行了修正( This procedure is experimental procedure for signal filtering. The main function is to carry the signal phase filter protection. Of the amplitude of the filtered signal computing problems were corrected)

emd分解中采用对称延拓消除边界效应，供大家参考学习(emd decomposition of symmetric extension used to eliminate the boundary effects)

说明：  飞机定位问题在航空的应用是十分广泛的，此源码是用matlab实现的，能够准确模拟出飞机在空中的定位。(positioning of the aircraft in the aviation application is very extensive, the source is realized using Matlab, to accurately simulate aircraft in the air positioning.)

说明：  　本文对变步长自适应滤波算法进行了讨论,建立了步长因子μ与误差信号e(n) 之间另一种新的非线性函数关系. 该函数比已有的sigmoid 函数简单,且在误差e(n)接近零处具有缓慢变化的特性,克服了Sigmoid 函数在 自适应稳态阶段步长调整过程中的不足. 由此函数本文得出了另一种新的变步长自适应滤波算法,并且分析了参数α,β的取值原则及对算法收敛性能的影响. 该算法有较好的收敛性能且计算量少. 计算机仿真结果与理论分析相一致,证实了该算法的收敛性能优于已有的算法.(In this paper, variable step adaptive filter algorithm to discuss the establishment of a step factor μ and the error signal e (n) between another new nonlinear function. The function has a sigmoid function than the simple and the error e (n) close to zero Department has a slow change in the characteristics of a Sigmoid function to overcome the steady-state phase in the adaptive step length adjustment during the process. this function, this paper gives another new variable step size adaptive filtering algorithms, and analysis of the parameters α, β the value principles and the convergence performance. The algorithm has better convergence performance easy to calculate. Simulation results and theoretical analysis, confirmed the convergence of the algorithm better performance than existing algorithms.)
