国外牛人写的聚类算法，是k-means算法的升级版(Written by foreign cattle clustering algorithm, k-means algorithm is an upgraded version of)

gm(1,1)灰色预测模型，可以进行各种预测。短期的电力负荷预测尤其的好。也可以进行中长期的预测，但是效果没有短期的好。(gm (1,1) Grey forecasting model can predict all kinds. Short-term load forecasting particularly well. Can also make long-term forecast, but they were not short of good.)

抽象类以及纯虚函数的相关笔记。Figure作为基类，派生出Circle，Square(Abstract classes and pure virtual functions related notes. Figure as a base class, derived Circle, Square)

drtoolbox降维工具箱程序包以及使用的范例 LLE，LTSA，ISOMAP，等( examples of drtoolbox use)

R/S分析法中如何求解重标极差，得到后使用最小二乘估计就可以得到，Hurst指数(R/S analysis method on how to solve the rescaled range, obtained after the least-squares estimation can be used, Hurst index)

绘出时域图，在时域上进行分析，提取时域特征值：绝对均值，标准差，有效值，方根幅值，波形指标等等，进行故障特征提取，识别故障(The time domain diagram is drawn and the time domain is analyzed. The time domain eigenvalues are extracted: absolute mean, standard deviation, effective value, square root amplitude, waveform index and so on. Fault feature extraction and fault identification are carried out.)

基于harris 的图像角点提取，并做改进，限制小区域内最多特征点数量(feature extraction by harris)

matlab很强大应用——pca的应用，希望对你有用，很好，很强大(Matlab is strong applications-the application of pca, hope to be useful to you, very good, very strong)
