MA 在迁移的过程中，动态决定节点是否需要进行数据融合 运算，以进一步降低MA 的能量消耗。(MA in the course of migration, determine the need for data fusion node operators to further reduce the energy consumption of MA.)

some exercices with matlab

说明：  一个利用Matlab绘图的教程，可以简单的绘制一些曲线。(A use of Matlab graphics tutorials, you can draw a number of simple curves.)

simple simulink file example

对非平稳信号进行分段、截取，再对处理过后的短时信号做短时傅里叶变换，分析其频谱特性，并找到各个时间节点的频率特性，以便分析不同事件段内的声音特征。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysis of the spectrum characteristics and frequency characteristics and find the different time node, in order to analyze the acoustic characteristics of different event period.)

说明：  经典蝙蝠算法，含越界检查，评价函数自己写(Classic bat algorithm, including out of bounds check, evaluation function written by yourself)

Matlab 加入高斯白噪声，并计算加入噪声后信号的自相关 和加入噪声后信号和理想信号的互相关 ，将以上参数代入函数中进行维纳滤波。(Matlab Gaussian white noise, and calculated after adding noise autocorrelation and added noise signal and the ideal signal cross-correlation signal, the above parameters into function Wiener filtering.)

这是小波包消噪程序，很简洁，在分析信号之前可能用得上(This is the wavelet packet de-noising procedure is very simple, you may need them before analyzing signals)

一维FDTD，MATLAB代码，可以绘制场量动图(One-dimensional FDTD, MATLAB code, you can draw the amount of field action figure)
