在MATLAB开发的遗传编程的源程序

使用MATLAB对DSB-AM进行仿真：双边带幅度调制的过程以及对其中所包含的对信号的频谱分析都可以通过MATLAB中的M语句及相关函数来实现。假如信号m(t)=cos(m)以dsb-am方式调制载波c(t)=cos(20*pi*t),所的信号为y(t)，并将采样频率定为 fs=100Hz,则可在MATLAB中设计程序对该幅度调制的结果进行仿真，绘制已调信号波形和频谱分析。(It is a example for DSB-AM based on MATLAB .)

说明：  用鲁棒控制方法来控制一个简单的二阶机械系统：质量块-阻尼器-弹簧系统。该系统是本科生实验教学中常见的控制实验装置。作为本书中的第一个案例，将针对该装置介绍三种控制器的详细设计方法，分析闭环系统的鲁棒稳定性和鲁棒性能。为了简化设计过程，此处仅考虑模型的结构扰动（参数扰动）。针对此例，介绍了matlab鲁棒控制工具箱（Robust Control Toolbox）一些鲁棒控制器设计指令。希望此章的学习不仅能够教授鲁棒控制系统设计方面的知识，也能够教会大家如何使用鲁棒控制工具箱。(Robust control method is used to control a simple second order mechanical system: mass damper spring system. The system is a common control experimental device in undergraduate experimental teaching. As the first case in this book, the detailed design methods of three controllers for the device are introduced, and the robust stability and robust performance of the closed-loop system are analyzed. In order to simplify the design process, only the structural disturbance (parameter disturbance) of the model is considered here. For this example, some robust controller design instructions of MATLAB robust control toolbox are introduced. I hope that this chapter can not only teach the knowledge of robust control system design, but also teach you how to use robust control toolbox.)

利用PCA算法进行人脸识别的源程序，供学习使用

前段时间由于项目需要，学习了下如何提取信号包络线的方法，主要是在希尔伯特变换之上，添加了优化算法，采用三次抽样的方法使包络线变得平滑。

说明：  本程序是基于方向优先权的机器人最优路径寻找算法，也可用于求解迷宫的最短路径,算法中是以100*100的格点为实例的，其中标0的位置为可行的点，标1的为障碍物，参考者可以根据自己的情况修改场地信息矩阵和起始点、目标点中间的算法不用修改 (This procedure is based on the priority direction of the robot to find the optimal path algorithm can also be used to solve the maze of the shortest path algorithm is 100* 100 grid points for the instance, which marked the location of 0 points as possible, standard 1 for the barrier, reference conditions can modify the site according to their own information matrix and the starting point, target points do not modify the middle of the algorithm)
