matlab 软件的simulink 实验室说明软件(simulink of matlab software note software laboratory)

说明：  窄带波束形成基本原理及基于matlab的源代码(The basic principles of narrow-band beamforming and the source code based on matlab)

改进的Salama网络拓扑随机生成算法通用Matlab程序，在随机抛撒节点的时候使用了K均值聚类，网络节点分布均匀且疏密得当，边的分布也比较均衡。(Improved algorithm for randomly generated network topology Salama General Matlab program, when the nodes in the random throw using K means clustering, the network node density distribution and appropriate, a more balanced distribution of the edge.)

严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计 优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大， 出来后学习率又还原 优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (A Matlab procedures in strict accordance with the BP network computing formula to design, the optimization design was carried out on BP network Optimization design of 1: YYY, that is O (k) in the formula, when the network into the flat area (<0.0001) learning rate increase, after learning rate and reduction Optimization of 2:v (I, J) =v (I, J)+deltv (I, J)+a*dv (I, J) )

基于EGM模型计算全球任一经纬度处的重力异常，垂线偏差(Global computing at any latitude and longitude based on gravity anomalies EGM model, vertical deviation)

MATLAB通信仿真中的simulink仿真全面讲解，菜鸟上手的讲点教材(MATLAB simulation of the simulink simulation of communication round talks, the rookie get started speaking point of teaching materials)

利用matlab，产生具有三个频率的跳频信号(the generation of jump-frequency signal)

This research work is used performence improvement of frequency.It is frequency division multiplexing.

说明：  Matlab中用于求解精确的单位阶跃响应的超调量与过渡时间的函数，详见函数说明(Matlab, used to solve the exact step response overshoot and the transition function of time, see function description)

This MATLAB code plot the aperture efficiency Vs the subtended angle. The user enter the value of n (2,4,6 or 8) and the code will plot and tell what is angle value that achieves max efficiency and the value of this efficiency.
