this code can rotate matixes and find the rotation angles

说明：  采用FDTD计算2维光子晶体的散射和透射的可执行程序小软件，修改输入文件可用于光子晶体的建模和计算，比较好用(FDTD calculation using two-dimensional photonic crystal scattering and transmission of the executable program small piece of software, modify the input file can be used for modeling and calculation of photonic crystals, compare easy to use)

实上，我们可以把系统框图中外编码器、交织器和内编码器三部分级联后的总体，看作一个级联码的编码器，同理，外译码器、去交织器和内译码器三部分级联后的总体构成了级联码的译码器。 本次仿真外编码采用（7，4）HAMMING码，内编码采用（2，1，3）卷积码。交织编码采用（7，4）卷积交织编码或循环等差交织编码。除特别说明外，交织编码采用前者即（7，4）卷积交织编码。 (failed to translate)

考虑了基站通过多个中继与多个用户的问题，基于背包问题提出了最优功率分配。(the optimal power allocation is presented based on knapsack problem for a system with a base station communication with multiple users assisted by multiple relay.)

说明：  uwb进行脉冲位置调制,并且进行相关接收,画出其图形(UWB pulse position modulation, and the associated receiver, to give their graphics)

子空间拟合类算法WSF的一种改进算法MVP，用于DOA估计。(Subspace fitting-like algorithm WSF An improved algorithm for MVP, for the DOA estimation.)

In this work, we present a novel evolutionary multiagent-based simulation tool, named as GAPatrol. Such system is devoted to the specification of effective police patrol route strategies for coping with criminal activities happening in a given artificial urban environment, which, in turn, mimics a real demographic region of interest.
