代码说明:

仿射加密法与单码加密法没什么不同,因为明文的每个字母分别只映射到一个密文字母。仿射密码的加密算法就是一个线性变换,即对任意的明文字符x,对应的密文字符为  ,其中,a,b∈Z26,且要求gcd(a,26)=1,函数e(x)称为仿射加密函数。

  • OSGFrameWork
    最近学习OSG,下载了FreeSouth大侠的一个MFC框架RambleSystem,自己学习了一下,新建了一个单文档程序,改了其中一些bug,和大家分享一下。单文档程序实现的功能非常简单,就是打开显示osg文件。不过仍存在一个问题,例如打开一些osg文件显示模型不理想,估计是视口设置有问题;另外打开一些osg文件出现内存泄露。(Recent study OSG, download heroes of an MFC framework FreeSouth RambleSystem, you learn a little, a single document, new procedures, some of which changed the bug, and share with you. Program realization of the function of a single document is very simple to open display osg file. However, there are still a problem, such as opening a number of osg file display model is not satisfactory, as the population estimate is set to have problems other osg files appear to open a number of memory leaks.)

    理论知识是用来指导具体实践的。本文在深刻理解通信系统理论的基础上利用 MATLAB 强大的仿真功能,设计了许多具体的通信系统仿真模型。在仿真模型设计过程中,本文对模型设计的目的、具体的结构组成、仿真流程以及仿真结果都给出了具体详实的分析和说明。(Theoretical knowledge is used to guide the specific practice. In this paper, a deep understanding of the theory of communication systems using MATLAB based on the powerful simulation function, the design of a number of specific communication system simulation model. In the simulation model of the design process, this article is designed on the model, the specific structural components, simulation and flow simulation results are given specific and detailed analysis and description.)
