经验模式分解程序（matlab）可以对输入信号进行经验模式分解(Empirical mode decomposition process (matlab))

main executing reference usage: observeWaveletDecompositionBenchmark_N_levels.m The objective is to illustrate wavelet decomposition, and to describe how operations may be done in the wavelet domain before the reconstruction. The demo decouples the wavelet operations (transform, operation in wavelet domain, and reconstruction) from the plotting. A PSNR and MSE describes the possible distortion (however minimal) of the forward and inverse wavelet transform. * Caveat: The image display may be subjected to the selected target image. The objective is to provide a simple framework for the understanding of working with wavelets.

本程序根据训练好的网络文件ANN.mat预测新的数据文件，得到均方误差，并画出预测数据和原数据的对比图。此程序运用到了很多Matlab编程中常用到的表达方式，还有一些神经网络编程的基本概念的表达，如归一化的表达(This procedure according to the trained network file prediction ANN.mat new data file, the mean square error, and painted the original data and prediction data comparison of Fig. This procedure applied to a lot of Matlab programming to the expression commonly used, and some neural network programming the expression of the basic concepts, such as the normalized expression)

计算微分方程系统的Lyapunv exponent,在非线性动力学和有关混沌的研究中非常有用。(calculated differential system Lyapunv exponent, Nonlinear Dynamics and Chaos in the study very useful.)

这是一个可用的求权重的程序，所求的是列的权重，作为函数的形式出现，可以直接调用，实在数据处理时编写的，可以直接用。(Seeking weight program is available, ask the weight of the column, as a function of the form appears, you can directly call, really data processing written can be directly used.)

说明：  脑电地形图matlab代码，可根据数值向量和通道位置文件绘制2D地形图(plot a topographic map of a scalp data field in a 2-D circular view (looking down at the top of the head) using interpolation on a fine cartesian grid.)

对地震剖面图求出某一区域的外源干扰的公式(The seismic cross-sectional view obtained in a region of exogenous interference formula)

说明：  实现了FCM模糊聚类算法，由matlab实现，可以直接使用(FCM clustering algorithm implemented by the matlab implementation, can be used directly)
