中文说明：三相光伏逆变并网的仿真，用MATLAB实现动态聚类或迭代自组织数据分析，用于时频分析算法，最终的权值矩阵就是滤波器的系数，通过matlab代码，对于初学者具有参考意义。
English Description：
Three-phase grid connected photovoltaic inverter simulation, using MATLAB to achieve dynamic clustering or iterative self organizing data analysis, for time-frequency analysis algorithm, the final weight matrix is that of the filter coefficients. Through the matlab code, for beginners has reference significance.
