Structure Tensor 的 matlab 实现 Tensor 源于对方向和密度的描述，可在局部描述2／3维数据的形态

基于FFT谱连续细化算法的高精度频率估计，这种算法可以精确到小数点后两位，这种算法与MUSIC法和ESPRIT法相比，计算量大大降低，而且精度非常高。(This procedure is based on the FFT spectrum continual refinement algorithm s high accuracy frequency， this algorithm may precisely to decimal point latter two, compared the MUSIC algorithm and the ESPRIT algorithm, the computation complexity reduces greatly, moreover the precision is high.)

主成分分析matlab程序，里面包含子程序，运用时直接调用主程序即可，可用于无监督模式学习(Principal component analysis matlab program, which contains a subroutine, the main program can be called directly when applying, can be used for unsupervised learning mode)

这是基于matlab的电路仿真,程序是自己改写的,还不多,希望大家多多交流.(This is based on Matlab circuit simulation, the process is write, and do not, We hope to conduct more exchanges.)

MATLAB Codes for Finite Element Analysis Solids andS tructures

内容：运用PM算法识别空间目标。程序中附有注释，可改变方向角，运算速度比music算法快，本人毕设程序，绝对可用。(Content: The use of PM space target recognition algorithm. Annotated program, you can change the direction of the angle calculation algorithm is faster than the music, I set up the program, absolutely free.)

说明：  该压缩包内为非线性格兰杰因果关系检验代码，欢迎大家下载(The compression package contains the non-linear Granger causality test code, welcome to download)

虽然奇异值分解（SVD）和特征值分解（EVD的）是行之有效的，可以通过先进的设施设备先进的算法，它不是通常所说，有一个内在的迹象，可以显着影响的不确定性的结论计算及诠释来自其结果。我们提供一个解决方案，标志模糊的问题确定了从奇异向量的内积和个人数据载体签署奇异向量的迹象。该数据可能有不同的载体，但它有它自身的定位和实际意义的选择方向，其中多数的向量点。这可以通过评估发现了内心的签署标志产品的总和。(Although the Singular Value Decomposition (SVD) and eigenvalue decomposition (EVD) are well-established and can be computed via state-of-the-art algorithms, it is not commonly mentioned that there is an intrinsic sign indeterminacy that can significantly impact the conclusions and interpretations drawn from their results. We provide a solution to the sign ambiguity problem by determining the sign of the singular vector from the sign of the inner product of the singular vector and the individual data vectors. The data vectors may have different orientation but it makes intuitive as well as practical sense to choose the direction in which the majority of the vectors point. This can be found by assessing the sign of the sum of the signed inner products. )
