FDM卫星通信仿真程序及一些辅助函数，共有六条上行链路(FDM satellite communication simulation program and some auxiliary functions, a total of six uplink)

这个是对PL-logdist和PL-lognormal的一个仿真。程序简单易懂，但是意义不小。有专门的画图子程序。(This is a PL-logdist and PL-lognormal a simulation. Procedures are simple, but the meaning is not small. Have a special drawing routines.)

Mean Shift 这个概念最早是由Fukunaga等人[1]于1975年在一篇关于概率密度梯度函数的估计中提出来的,其最初含义正如其名,就是偏移的均值向量,在这里Mean Shift是一个名词,它指代的是一个向量,但随着Mean Shift理论的发展,Mean Shift的含义也发生了变化,如果我们说Mean Shift算法,一般是指一个迭代的步骤,即先算出当前点的偏移均值,移动该点到其偏移均值,然后以此为新的起始点,继续移动,直到满足一定的条件结束. 用matlab实现mean shift算法仿真(Mean Shift the concept was first used by Fukunaga et al [1] in 1975 in an article on the probability density function estimation of gradient raised its original meaning, as its name implies, is the offset of the mean vector, where is the Mean Shift a noun, it refers to a vector, but with the Mean Shift the development of the theory, Mean Shift the meaning has changed, if we say that Mean Shift algorithm, generally refers to an iterative steps, namely, first calculate the current point Mean offset, move the shift points to its average, and then as a new starting point and continue to move until the end to meet certain conditions. realize using mean shift algorithm matlab simulation)

这个程序即可以读取XMl文件并转换成matlab结构体，也可以把matlab结构体转换成xml格式存放。xml是最被看好的数据存储方式，xml格式的通用性减轻了大家编写格式转换代码的痛苦。(This process that can read XML files and converted into matlab structure can also be put into matlab structure xml format. xml are the most promising way of data storage, xml format, reducing the U.S. generic format conversion code preparation suffering.)

从国外大学上下的Levenberg算法程序(From foreign universities Levenberg algorithm program from top to bottom)

说明：  一个立体匹配的算法，对于研究视觉立体匹配的同学有一定的作用。(A stereo matching algorithm, for the study of visual stereo matching students to a certain extent.)
