实现ID3算法，在结果中以树表示出来。决策树是对数据进行分类，以此达到预测的目的。该决策树方法先根据训练集数据形成决策树，如果该树不能对所有对象给出正确的分类，那么选择一些例外加入到训练集数据中，重复该过程一直到形成正确的决策集。(ID3 algorithm to achieve, in the results that come out to the tree. Decision tree is to classify the data, thus achieving the purpose of prediction. The decision tree training set of data according to the formation of the first decision tree, if the tree can not give the correct classification of all objects, then select a number of exceptions to the training set data, repeat the process until the correct decision set.)

一种用Newton-Rapson Method来计算能量的Matlab code(Newton-Rapson Method to determine the slack bus power( 3 buses)/)

function [L,C] = kmeans(X,k) KMEANS Cluster multivariate data using the k-means++ algorithm. [L,C] = kmeans(X,k) produces a 1-by-size(X,2) vector L with one class label per column in X and a size(X,1)-by-k matrix C containing the centers corresponding to each class.

一个在认知无线电中的能量检测和周期检测的仿真源代码(An energy detection and cycle detection in cognitive radio simulation source code)

该段代码可用于加速度信号的积分求得位移。使用的是频域积分方法，设置合适的上下限截止频率可较好的复现实际路面的位移高程。(This code can be used for integration of the acceleration signal obtained displacement. Using a frequency-domain integral method, set the appropriate upper and lower cutoff frequency displacement elevation better reproduce the actual road.)
