定时同步的文章，很值得看一看，算法简单，精度很高！(Timing of the article, well worth a look, a simple algorithm, high precision!)

说明：  主成分分析和独立成分分析,分别处理降维问题和盲信号分离问题(Principal component analysis and independent component analysis, dimensionality reduction, respectively, deal with the problems and blind signal separation)

Matlab code for computing the root(s) of a maximum likelihood function.

四元数Hartley仿射变换。对研究四元数Hartley仿射变换的不变性有帮助(quaternion hartley affine transform～～)

matlab的psat软件用于潮流计算，连续潮流计算，小扰动分析，分岔分析等等，方便实用(The psat matlab software for flow calculation, continuous flow calculation, the small perturbation analysis, bifurcation analysis, etc., convenient and practical)

高斯过程回归算法工具箱，很好用的，我用过(Gaussian process regression algorithm toolbox, well used, I used)

EMD或者LMD的能量密度与其平均周期的乘积K值，当K值发生较大变化的时候，证实该分量为白噪声，可以剔除，将剩下的分量进行重构，达到去噪的目的。(The product of K EMD or LMD energy density and average cycle value when the K value was changed greatly, the component for white noise can be eliminated, the remaining components are reconstructed to achieve the purpose of de-noising.)

This code is improving parts of the image with imcrop according to the 2-D histogram (mesh).
