五种灰色关联度分析matlab代码

该代码可是先matlab音乐键盘仿真，对应按键可在键盘上的按键找到(The code can be realized matlab music keyboard simulation, corresponding to the sound of keys can find on the keyboard keys )

水文学 马尔科夫链在各个月份间的转移频率计算---以丰平枯为例(Hydrology Markov chain transfer frequency is calculated for each month between the abundance of flat to dry as an example---)

说明：  采用5点3次平滑算法和SG平滑算法对曲线进行平滑处理，结果良好(The curve is smoothed by 5-point 3-order smoothing algorithm and SG smoothing algorithm, and the result is good.)

说明：  本程序主要是包含了ESPRIT算法性能的一维仿真和二维的仿真。(This procedure includes the ESPRIT algorithm is mainly one-dimensional simulation of the performance and two-dimensional simulation.)

标准粒子群算法，改进粒子群算法，希望大家能用上(Standard particle swarm optimization, improved particle swarm algorithm, hope everyone can be on the)

LEACH (Low Energy Adaptive Clustering Hierarchy) is designed for sensor networks where an end-user wants to remotely monitor the environment. In such a situation, the data from the individual nodes must be sent to a central base station, often located far from the sensor network, through which the end-user can access the data.

说明：  seir模型模拟传染病 人在康复以后产生了抗体就不会再得病。不同于SIS模型，我们在模型中引入康复者(The Recovered)，用 [公式] 表示，并满足总人数 [公式] 。这个时候就是SIR模型。一旦变为康复者，就不会再传染，即在概率传递过程中，一旦变为康复者，就没有概率再次转移为感染者或者易感者。我们假设感染者变为康复者的概率为我们来看下SIR模型的微分方程(SEIR model simulating infectious diseases)
