说明：  战胜MATLAB的50道经典习题，MATLAB最主要的就是练，希望对大家有用。(The 50 classic victory over MATLAB Exercises, MATLAB is the most important practice and hope for all of us.)

一般路径损耗模型分为自由空间传播模型和对数距离路径损耗模型，本程序建立以上模型。(Generally divided into free space path loss model propagation model and logarithmic distance path loss model, the program to build more models.)

以Simulink为主要工具介绍了系统仿真方法与技巧，包括连续系统、离散系统、随机输入系统和复数系统的仿真。介绍了模声封装技术、电力系统模块集、非线性系统设计模块集、S-函数编写与应用、Stateflow有限状态机、虚拟现实工具箱等中高级使用方法，最后还介绍了半实物仿真技术与实时控制技术。(Simulink as the main tool to introduce a system simulation methods and techniques, including continuous systems, discrete systems, stochastic input system and the simulation of complex systems. Introduce a sound module packaging technology, power system module set, non-linear system design blockset, S-function of the preparation and application, Stateflow finite state machine, virtual reality and other high use of the toolbox, and finally also introduce a semi-physical simulation technology and real-time control technology.)

说明：  设计一个有干扰的直接序列扩频通信系统， PN码由m序列产生器产生，经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”，将接收信号进行解扩，判决，得到用户的信号检测结果，绘制不同的扩频增益（增益值为10，30，50）下，误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including &quot useful signal+ Gaussian white noise+ interference&quot , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)

这是有关,matlab的各种窗函数的设计事例.(It is about, matlab window function of various design examples.)

simulink仿真，电力系统发生故障时，电力系统稳定器作用，使发电机转子功角一致性和频率同步。(Simulink simulation, when the power system fault, the power system stabilizer function, so that the generator rotor power Angle consistency and frequency synchronization)

This paper provides the review of literature benchmarks (test functions) commonly used in order to test optimization procedures dedicated for multidimensional, continuous optimization task. Special attention has been paid to multiple-extreme functions, treated as the quality test for “resistant” optimization methods (GA, SA, TS, etc.)
