《精通simulink系统仿真与控制》，学习simulink不可多得的好书，已经很难找了(" Proficient simulink simulation and control" , learning simulink rare books, has been hard to find)

在matlab这个平台上对平面，立体等单元进行有限元力学分析(Finite element stress analysis in the the matlab platform on the plane, three-dimensional unit)

二维数据平滑，跟定二维数据，每9个点拟合，中间点带入拟合的曲线，得到平滑后的数据(2 d data smoothing, with 2 d data, fitting every nine points, intermediate points to the fitting curve, get data after smoothing)

说明：  关于gauusian函数的matlab代码，角点提取时会用到(About gauusian function matlab code that will be used corner detection)

本程序适用于自适应波束形成的几种算法的matlab仿真。(This procedure applies to adaptive beamforming algorithms for the matlab simulation.)

One program to simulation light passing through a glass sphere. It is interesting and can be used in geometric optics.

基于matlab的二阶微分动力学的智能体flocking数值模拟，其中每个智能体的动力学用微分方程来描述，给出每个个体组后的最后位置与运动方向。(a matlab code for second-order differential multi-agent flocking simulation, each agent s dynamics is described by using differential equation. it gives the figure of all agents position and velocities.)

快速可靠的GPS (全球定位系统)系统仿真可对双频GPS 接收机的设计、接收算法的研究 提供有效的帮助。文中详细介绍了在MatLab/Simulink 环境下GPS 系统仿真平台构建的基本方法。 首先分析了GPS 系统的各个环节，说明了各模型在仿真中的实现方法；然后给出了完整的系统仿 真框图，并在此平台上实现了GPS L2 载波相位跟踪的仿真。结果表明该仿真平台有效、可靠(Fast and reliable GPS (Global Positioning System) system simulation of dual-frequency GPS receiver design, receiver algorithm to provide effective help. Text in detail in the MatLab/Simulink environment GPS system simulation platform to build the basic method. First, we analyze the various segments of GPS systems shows that the model in the realization of simulation methods and then given a complete system simulation block diagram, and on this platform realize the GPS L2 carrier phase tracking of the simulation. The results show that the simulation platform for effective, reliable)
