This is a program to study the dynamic instability of cylindrical shell due to parametric excitation.

种群中的博弈个体收益变化的情况下，给出了生灭过程下，合作与背叛两种策略的演化过程(The case of population changes in yield Game individuals are given under the death process, collaboration and betrayal of the evolution of the two strategies)

说明：  通信原理课本中的一些实例代码，方便大家使用(Communication principles in the textbook of some examples of code, easy to use)

In short, to-the-point chapters, Practical C++ Programming covers all aspects of programming including style, software engineering, programming design, object-oriented design, and debugging. It also covers common mistakes and how to find (and avoid) them. End of chapter exercises help you ensure you ve mastered the material. Steve Oualline s clear, easy-going writing style and hands-on approach to learning make Practical C++ Programming a nearly painless way to master this complex but powerful programming language.

主要介绍了matlab的一些简单的命令，和它的功能以及使用方式，非常适合初学者。(Matlab introduces some simple commands, and its features and use, ideal for beginners.)

Simulink 控制VR环境中的小车。小车有5个距离传感器，能够慢慢学会避开墙壁和障碍物。小车采用加强学习（Q learning），采用神经网络对Q函数逼近。由于使用了模拟退火，小车在开始的时候会经常撞击障碍物，10次后基本就不会再撞了。 小车的外观模型使用了"w198406141"在本论坛的虚拟现实区发布的VR模型。(VR environment Simulink control car. There are 5 car distance sensor, can gradually learn to avoid walls and obstacles. Car used to enhance learning (Q learning), using neural networks Q function approximation. As the use of simulated annealing, the car will start when the regular crash barrier, 10 times the fundamental will no longer hit. The appearance model used car " w198406141" in this forum area of virtual reality VR model release.)

用 matlab实现均值滤波去高斯白噪声 用 matlab实现中值滤波去噪声 用理想低通滤波器在频率域实现低通滤波(Mean filter with matlab to implement Gaussian white noise with median filter matlab to achieve the ideal low-pass filter with the noise in the frequency domain low pass filter)

时域处理算法，本源码是关于时域预处理放面的内容，包含简易的算法(Time domain processing algorithms, the source is placed on the surface pretreatment time-domain content, including a simple algorithm)

关于matlab中变量的传递问题，希望对大家有用(on Matlab variable transmission problems, in the hope that it may be useful to)

关于matlab 和C 混合编程的一个文档材料，推荐看一下。(a file about the programme of matlab and C.)
