m_PN
说明: 伪随机码或称PN码,是扩频通信中不可缺少的一种序列。扩频通信,简单的说来就是通过一组相关性很强的伪随机序列,使原有的信号按照伪随机序列的特性出现。从波形上看,原有信号完全淹没于随机的噪声中,达到隐藏信号和抗干扰的目的。接受方只要有相同的伪随机序列,就可以通过伪随机序列很强的相关性将信号还原出来。而m序列,是扩频系统中最长用的伪随机序列。下面的代码就是基于matlab的生成m序列的代码,通过改变初始多项式的值,就可以生成不同阶数的m序列。(Pseudo-random code or PN code, spread spectrum communication is indispensable to a sequence. Spread spectrum communication, a simple to say that the adoption of a group of highly related to pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence there. From the wave point of view, the original signal completely submerged in the random noise to hide the purpose of signal and interference. As long as the recipient has the same pseudo-random sequence, the pseudo-random sequence can be a strong correlation to restore the signal out. And m sequence spread spectrum system is the longest of the pseudo-random sequence used. The following code is generated based on m sequences of matlab code, by changing the value of the initial polynomial, we can generate a different order of the m sequence.)

正方形ABCD的4个顶点各有1人.在某一时刻,4人同时出发以匀速v=10m/s按顺时针方向追逐下一人,如果他们始终保持对准目标,则最终按螺旋状曲线于中心点O.试求出这种情况下每个人的行进轨迹(Four vertices of square ABCD each one. At a time, 4 people starting at a uniform v = 10m/s in a clockwise direction chasing the next person, if they remain at the target, then press the spiral curve in the final Find the center point O. This road track of each person)

说明: 遗传算法matlab工具
1.工具箱文件拷贝至Matlab文件夹下,具体路径为:C:\program files\MATLAB\R2009a\toolbox。
2.工具箱路径加入Matlab文件路径之中。
流程为:File-->Set Path-->Add Folder。即,将C:\program files\MATLAB\R2009a\toolbox\文件夹加入该路径系统中。
3 重新启动Matlab,运行即可。
4 一般情况下,会出现如下情况。
安装遗传工具箱后出现问题:Warning: Name is nonexistent or not a directory: \afs\eos\info\ie\ie589k_info
解决方案:
将C:\program files\MATLAB\R2009a\toolbox\文件夹下的startup.m文件中的路径“\afs\eos\info\ie\ie589k_info\”改为goat当前所在的目录,“C:\program files\MATLAB\R2009a\toolbox\”即可。(Genetic algorithm matlab tool 1. Matlab toolbox files are copied to the folder, the specific path is: C: \ program files \ MATLAB \ R2009a \ toolbox. 2. Matlab toolbox add the file path into the path. Process is: File-> Set Path-> Add Folder. That is, the C: \ program files \ MATLAB \ R2009a \ toolbox \ folder by adding the path system. 3 Restart Matlab, can be run. 4 Under normal circumstances, there will be the following. Problems after installing genetic toolbox: Warning: Name is nonexistent or not a directory: \ afs \ eos \ info \ ie \ ie589k_info \ Solution: C: \ program files \ MATLAB \ R2009a \ toolbox \ startup folder under the . m file path " \ afs \ eos \ info \ ie \ ie589k_info \" to the current directory where the goat, " C: \ program files \ MATLAB \ R2009a \ toolbox \" can be.)
