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.)

实现了用DCT变换进行噪声估计的功能，代码已经实现过了，可用哦。(DCT transform noise estimation function, the code has been achieved, can be used.)

matlab中广义最小残量法的m文件 包含arnoldi过程 和 gmres两部分 (matlab generalized minimum residual method m file contains arnoldi the process and gmres two parts)

该函数的功能使根据所给的数组，根据不同的组合个数，将数组分成不同的组, C-m-n C m 取 n,列出所有的组合！(list the differant units...)

上传的为粒子群优化算法的仿真程序，MATLAB编程。(Particle Swarm optimization)

基于AIC方法用MATLAB估计信源个数的程序 ( estimate the singal source number using AIC)

说明：  一种新型自适应信号时频处理方法，特别适用于非线性非平稳信号的分析处理。(A new adaptive signal time-frequency processing method is proposed, which is especially suitable for the analysis and processing of non-linear and non-stationary signals.)
