电力系统课程设计，PQ潮流算法源程序，IEEE节点适用。(Power systems curriculum design, PQ flow algorithm source code.)

单相离网逆变器，半桥式I型结构，三电平逆变。simulink仿真模型(Single-phase off-grid inverter, half bridge type I structure, three level inverter.Simulink simulation model)

首先对图像网格化，选择网格坐标位置作为标记种子点添充目标物体。matlab (first images of the grid, select grid coordinates position as a marker seed Tim charge of target objects. Matlab)

亲测可用的EMD分析，直接调用改函数即可。具体可看代码说明部分，或者在matlab里help emd(EMD analysis of pro-test available, direct call function can be changed. Specific instructions can look at the code section, or help emd in matlab in)

说明：  MATLAB的诸多例题和解法，对于matlab基础学习和指导很有用。多大上百例题。(Example and solution of many MATLAB for matlab-based learning and guidance very useful. How hundreds of Example.)

说明：  矩量法解电场双位方程求线天线表面电流分布，方向图及辐射阻抗(Moment Method Solution of the electric field equation for a double-wire antenna surface current distribution, radiation pattern and impedance)
