Matlab Implimentation of Exact Solution for the n-layer Sphere Problem

说明：  以truetime-1.5为例说明truetime工具箱的安装方法，很实用！！(An example to truetime-1.5 truetime toolbox installation method, it works! !)

这是根据提交的亚历山大Gramfort的“MATLAB的网状到PDF与三维交互对象“。他的计划将允许网数字转换成3D PDF格式。然而，他的代码只允许一个层进行转换，并不会启用的透明度。 本意见书不创建最终的PDF。它产生的U3D文件，然后可以使用到PDF的Adobe Acrobat Pro文件插入。本文件还允许多层网格，以创建，并为每个层的透明度指定。 此代码包含一个函数（installGoogleArchive.m），它会自动下载并安装所需的中间数据格式转换（IDTF）进入最后的通用3D（U3D）文件的二进制文件。此代码还只包括转换器的Windows版本。(This submission is based on Alexandre Gramfort s "matlab-mesh-to-pdf-with-3d-interactive-object". His program allows meshes to be converted into 3D PDF figures. However, his code only allows a single layer to be converted, and does not enable transparency. The present submission does not create the final PDF. It generates the U3D file which can then be inserted into a PDF file using Adobe Acrobat Pro. This submission also allows multilayer meshes to be created, and for the transparency of each layer to be specified. This code includes a function (installGoogleArchive.m) which will automatically download and install binaries required to convert the intermediate data format (IDTF) file into the final Universal 3D (U3D) file. This code also only includes the windows version of the converter.)

连接各路口节点，统计道路条数，求出各道路的长度，并求出所有顶点对间的最短距离(Connect each node of the intersection, statistics, road number, find the length of the road, and calculated the shortest distance between all vertices)

在matlab环境下，编程实现用拉普拉斯算子改善图像的反差增强程序(In the matlab environment, programming with Laplacian to improve image contrast enhancement procedure)

直方图是用面积表示各组频数的多少，矩形的高度表示每一组的频数或频率，宽度则表示各组的组距，因此其高度与宽度均有意义。 程序提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。 (Histogram is that each group size the number of frequency, the height of the rectangular frequency of each group said that the number or frequency, the width of that group from each group, so the significance of height and width of both. Extraction procedures need a lot of parameters histogram features, such as mean, variance, skewness, kurtosis, energy and entropy.)
