说明：  在扩频系统中再如不同得衰落的情况进行仿真(in spread spectrum systems in different Another example of the decline of Simulation)

说明：  EDA经典算法PBIL程序，与大家分，共同进步(PBIL algorithm EDA classical procedures, and that we can progress together)

power_SOFC.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_SOFC.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

一束光通过一个透明圆柱体，圆柱后有一个屏幕，程序最终反映屏幕上的 图象随圆柱半径的变化而变化。其中光强分布是采用相干叠加原理，因为其中采 样点数目不足，所以光强分布的结果和真实的有一定差距。增加采样点数目和改 变采样点范围能够改善输出光强的结果逼真程度。(一束光through a transparent cylinder, a cylindrical post-screen process will ultimately reflect the on-screen image with the cylindrical radius change. Light intensity distribution of which is the principle of coherent superposition, because the insufficient number of sampling points, so light intensity distribution of the results and have some real gaps. Increase in the number of sampling points and to change the scope of sampling points can improve the outcome of the output light intensity the degree of realism.)

采用动态规划方法实现的目标分配，后面有MATLAB代码(Solving Weapon Target Assignment Problem with Dynamic Programming)

这是我多年MATLAB编程的技巧汇总，希望对大家有用。里面包含命名规则，怎样优化程序等等。(This is my years of MATLAB programming skills summary, I hope useful for everyone. Which contains the naming rules, how to optimize procedures.)

实现对QPSK的零中频解调方案，适用于各种环境(To achieve zero intermediate frequency demodulation of QPSK simulation)

模糊逻辑控制器的谐波最小化。出现了给用户提供优质电能的问题。这是由于网络中非线性负载的增加，构成了电网的谐波污染源，产生了许多干扰，干扰了电气设备的优化运行。本文提出了消除非线性负载引入的谐波的解决方案。利用Matlab Simulink对有源电力滤波器（APF）在稳态和暂态过程中对非线性负载产生的谐波和无功功率进行了补偿和分析。仿真方法对有源电力滤波器的实用性得到了证明，利用MATLAB SIMULINK具有更好的电能质量洞察力，以开发基于有源电力滤波器的新型模糊逻辑控制器(This is due to the increasing presence in network of nonlinear loads.They constitute a harmonic pollution source of the network, which generate many disturbances, and disturb the optimal operation of electrical equipments. This work, proposed a solution to eliminate the harmonics introduced by the nonlinear loads. It presents the analysis and simulation using Matlab Simulink of a active power filter (APF) compensating the harmonics and reactive power created by nonlinear loads in steady and in transients. The usefulness of the simulation approach to APF is demonstrated , have a better power quality insight using Matlab Simulink in order to develop new fuzzy logic controller based active power filte)

说明：  自编多尺度样本熵程序，实例中用于一段轴承故障数据，简单易懂。MultiscaleSampleEntropy函数中的SampleEntropy也可以单独拎出来计算单个样本熵。(Multi scale sample entropy is used for a section of bearing fault data, which is easy to understand. SampleEntropy in the MultiscaleSampleEntropy function can also be picked up separately to calculate the entropy of a single sample.)
