s变换程序

说明：  动力学系统的分岔图的计算程序，高维混沌系统的分岔图(chaos of dynamical system)

先做灰階圖片，再利用IMHIST來做統計，在做SMOOTH來讓使用者更容易了解圖片的特色 (Grayscale images do first, and then use IMHIST do statistics, SMOOTH do to make it easier for users to understand the characteristics of the picture)

说明：  求正弦信号和余弦信号的傅里叶变化，以及图形之间的转变(Sine signals and cosine signals request the Fourier transform, and the graphics change between)

用以下的语句即可实现序列图像的组合。本人试了很多程序终于发现此妙招，再次感谢pudn提供的各种便利的下载，对于学者我也会多多发表自己研究的代码。(With the following statement to achieve a combination of image sequences. I have tried many programs and finally found this coup, thanks again pudn provide a variety of convenient download for academics, I also published a lot of their own research code.)

matlab图像处理程序，很实用的，图像多分辨率金字塔(matlab image processing procedures, very practical, multi-resolution image pyramid)

使用个股日内髙频收益率计算己实现值进行分析,同时计算得到二阶矩 和高阶矩值并进行对比。本文根据己实现量的大小将所有样本股分为己实现值由 小到大的姐别,分别跟踪各股票组合的收益,探索预期收益与个股己实现值之间 的变化关系,然后将分组的结果应用于多空策略,为提高资产配置收益提供参考。 同时,将各己实现变量和各类对预期收益产生影响的控制变量放在一起构建 Fama-MacBeth截面回归,分析高频已实现量是否具有定价能力。(The realized value is calculated by using the daily gust rate of return of individual stocks, and the second-order moments are obtained by calculating at the same time. Comparisons are made with higher order moment values. This paper divides all sample stocks into realized values according to the size of realized stocks. Sisters from small to large track the earnings of each stock portfolio, and explore the relationship between expected earnings and the realized value of each stock. Then the grouping results are applied to the multi-empty strategy to provide reference for improving asset allocation returns.)

用mathlab解关于卫星轨迹图的微分方程组, 简单实用的例子,能从中知道如何编写程序, 并如何画图.可直接在matlab7.0中运行. 以及有关于复杂网络的matlab源程序，供致力于复杂网络仿真研究的同仁参考！(Appollo satellite s trace (Differential equation))
