通信相关技术文档，关于能效方向，无线传输中的能耗控制(Communication related technical documents, about the direction of energy efficiency, energy consumption of wireless transmission control)

本段代码实现了手动选点的matlab配准，在此代码中只选择了3对控制点，同时从结果可以看出手动选点配准的不精确性，为自动选点配准算法的提出提供了实验依据(This code implements manually selected point matlab registration, in this code to select only the three pairs of control points, and the results can be seen from the point of registration manually selected imprecision, with the choice of site for the proposed automatic registration algorithm provide an experimental basis)

1 本程序通过Mallat算法实现小波变换 2 本程序能打开任意长宽比的bmp图像，正方形的raw图像(Through a process of wavelet transform Mallat Algorithm 2 the procedure to open the bmp images of arbitrary aspect ratio, the square of the raw image)

Logistic映射与奇异吸引子 一、logistic映射---通向混沌的道路 混沌系统，由于其行为的复杂性，往往认为其动态特性（运动方程）也一定非常复杂，事实并非如此，一个参量很少、动态特性非常简单的系统有时也能够产生混沌现象，以一维虫口模型为例，假设某一区域内的现有虫口数为yn，(logistic实现6蛛网迭代)

说明：  信号与系统实验一：连续时间信号 1.1 表示信号的基本MATLAB函数 1.2 连续时间复指数信号 (Signal and system experiment: a continuous time signal)

给你一个非常大的整数x，(-10^400 <=x<= 10^400)，请统计x的每一位，分别输出9,1,2出现的次数. Input 一个大整数 Output 一共三行，第一行是9出现的次数，第二行是1出现的次数，第三行是2出现的次数。 Sample Input 912912912910915902 Sample Output 6 5 4(Statistical figures)
