Arnold变化~~~matlab 含逆变换及周期计算(Arnold)

说明：  基于想要的主成分数量和精确度，采用matlab的pca函数进行主成分分析(Based on the desired principal component and accuracy, PCA function of MATLAB is used for principal component analysis)

输入线性方程组的增广矩阵，运行就能求解出方程解~(Input linear equations augmented matrix, run out the equations can be solved ~)

在matlab中，利用全局阈值对图像进行图像分割，得到有用的区域(Global threshold image in matlab for image segmentation, get useful area)

This code performs likelihood ratio test (LRT) for VAR model to determine optimal lag length, constant term is automatically included. Test is performed on contiguous lags, thus DOF=neqn^2*1. Guido Travaglini, 06.15.2011

对matlab编写的积分函数做了总结，包括各种积分函数和它的matlab程序。(The integral function on matlab to do the preparation of a summary, including a variety of integral function and its matlab program.)

Perfect matlab facetracker, detects eyes, mouth and face.
