Enhancement of LEACH

较为精确的逆变器仿真模型，包括控制系统，可作为初学者的重要参考,很有参考价值(More accurate simulation model of inverter, including the control system can be used as important reference for beginners，a good reference)

3D cubic-cell yee space lattice with simple outer boundary conditions (PEC sheets). the time-step relation cdt=d/sqrt(3)

离散函数matlab基本用法卷积与循环卷积描述及连续信号幅度谱包络(Discrete convolution function matlab basic usage and circular convolution description and continuous signal amplitude spectral envelope)

说明：  R/S分析，matlab程序，虽然比较繁琐，但还好使，请多多关注(R/S)

说明：  通过经验模态分解emd波形分割，将脉冲波形分为多个部分，基于EMD的时频分析方法既适合于非线性、非平稳信号的分析(By empirical modal decomposition emd waveform segmentation, the pulse waveform is divided into several parts, and the time frequency analysis method based on EMD is suitable for nonlinear and non-smooth signal analysis)

假定半波长间隔均匀分布线列布阵的阵元数N=16，若入射平面波为f=62.5Hz的正弦信号，信号持续时间为0.4s， 系统采样频率 =1 KHz,阵列加权为均匀加权，分别给出 a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时，指向90度的波束形成器的输出序列； b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives: a) 90 degree response when incidence angles are: 0: 10: 100 degrees b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )
