给出Henon的模型x(i+1)=1+y(i)-a*x(i)^2 y(i+1)=b*x(i) (Henon model given x (i+ 1) = 1+ Y (i)-a* x (i) ^ 2 y (i+ 1) = b* x (i))

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)

脑部增长 阈值处理分析，英文论文，挺有用(Processing and analysis of brain growth threshold, the English papers, quite useless)

C#小波分析源程序，不同于matlab，完全底层的代码(C# source wavelet analysis, unlike matlab, full underlying code)

自编求自相关的函数，可以实现不同序列的自相关(zibianqiuzixiangguandehanshu，keyishixianbutongxuliedezixiangguan)

说明：  它主要研究的是多因变量对多自变量的回归建模，特别当各变量内部高度线性相关时，用偏最小二乘回归法更有效。另外，偏最小二乘回归较好地解决了样本个数少于变量个数等问题。 偏最小二乘法是集主成分分析、典型相关分析和多元线性回归分析3种分析方法的优点于一身。它与主成分分析法都试图提取出反映数据变异的最大信息，但主成分分析法只考虑一个自变量矩阵，而偏最小二乘法还有一个“响应”矩阵，因此具有预测功能。(It is mainly a result of the study is a multi-variable regression modeling and more independent variables, especially when the internal height of each variable linear correlation, partial least squares regression method is more effective. In addition, partial least squares regression solves the number of samples is less than the number of variables and other issues. Partial least squares method is a set of principal component analysis, canonical correlation analysis and multiple linear regression analysis of the advantages of the three methods in one. It is the principal component analysis are trying to extract the maximum information reflects data variability, but the principal component analysis considers only one independent variable matrix, and partial least squares and a &quot response&quot matrix, predictive capabilities.)

使用MATLAB语言实现图像均衡化，不调用内部函数(Using the MATLAB language to implement the image equalization, does not call the internal function)

常见的潮流程序主要采用直角坐标来进行，本程序采用极坐标对简单输电网系统潮流进行计算(Common trend of the procedure used mainly for rectangular coordinates, polar coordinates, the program uses a simple grid system to calculate the trend)
