The architecture of this set of codes and the interaction among them is shown in Figure 1.
The main testing code main code.m calls the code riemann grad unit opt.m that performs
Riemannian optimization under unitary matrix constraint. Steepest Descent/Ascent
(SD/SA) algorithm (see Table 3.2 in [1]), Conjugate Gradient (CG-PR, CG-FR) algo-
rithms (both Fletcher-Reeves and Polak-Ribi`ere formulas, see Table 3.3 in [1]), are im-
plemented. This code further calls the codes implementing line search methods: Armijo
method geod search armijo.m, as well as the polynomial and DFT-based approximation

使用鏡子鏡射的原理，也就是將接收點鏡射之後，求取傳送點與接收點的距
離，而因為公式(1)及公式(8)，可知角度與距離有關係，可以使用這個公式來直
接代入公式(10)之中。(. The receiver is located at the center of a 50-m*50-m room and
transmitter is moved along a straight from 2m to 20m from the receiver.
Show the received power in decibels versus distance for the
LOS path, and include all the first-, second-,third-order reflections.

论文调研了复杂网络的结构特征，基于复杂网络的方法对在线社会网络的多种属性进行了分析，并利用MATLAB仿真工具对在线社会网络数据源进行了仿真，论文重点分析了在线社会网络的度分布、集聚系数、平均最短路径三个基本特征量，仿真实验结果表明在线社会网络具有小世界特性和无标度特性；然后，基于节点收缩的方法对网络节点重要性进行评估，根据节点重要度找出在线社会网络中的核心节点；进而，采用标签传播算法对在线社会网络进行社团划分，改进了算法的结条件，可在不影响划分结果的前提下，大大提高了运算效率。(Studies show that many social networks have the characteristics of the complex network, researching the basic characteristics of the network can help us to understand the various characteristics of social network By researching the importance of network nodes, we can find the Hub node of the network, it provides the basis of preventing the malicious attacks, protecting critical node or getting a better network transmission By researching the community structure of network can help us understand the relationship between the individual networks and achieve the maximization of network availability.)
