Structured Optimal Graph Feature Selection 对图像样本进行特征选择，使用自学习算法，然后得出相似度矩阵S(% Input % X: dim*num data matrix % gamma: coefficient of L21 % d: projection dim of W(dim*d) % c: number of clusters % k: nearest neighobrs %Output %id: sorted features by ||w_i||_2)

地震资料中反褶积MATLAB数据处理包。包括了预测反褶积，脉冲反褶积，稀疏反褶积等。对于地震资料处理有极大实用价值。(Seismic data deconvolution MATLAB data processing package. Including predictive deconvolution, pulse deconvolution, such as sparse deconvolution. For the seismic data processing has great practical value.)

一个自己编写的基于简化算法的单因变量的偏最小二乘回归，附带建模预测及奇异点的鉴别。(I have written a simplified algorithm based on a single by partial least squares regression, with model prediction and singular points of differentiation.)

用于直线拟合的matlab程序，用法请见函数内部的使用说明(linear fitting for the Matlab procedures, and applying the function see internal use)

说明：  可以降维分析，还有bp神经网络，非常方便学习。大家可以随意下载，(Dimensionality reduction analysis)

说明：  pq分解法都潮流计算，适合电力系统都人员使用，作为参考(pq)

一个UPF的例程，内含matlab源代码和相关的文档资料（英文），对UPF的基本原理有详细的介绍(a UPF of routines, containing Matlab source code and related documentation information (English), UPF of the basic tenets is described in detail)

非线性系统的模型阶次辨识+模型系统辨识，非常有效(Model order nonlinear system identification+ model system identification, is very effective)
