eof主成分分析，供高校本科生研究生使用，气象海洋专业(eof principal component analysis for the use of university undergraduate students, professional marine meteorology)

Matlab function to generate a random vector with entire values without repetition.

形态学中的腐蚀和膨胀运算。首先，对图像进行低通滤波，消除细小噪声的干扰。 在滤波时，没有采用传统的中值滤波器，而是采用顺序统计滤波器ordfilt2(Erosion and dilation operation in morphology. Firstly, the image is filtered by low pass filtering to eliminate the interference of small noise. In filtering, the traditional median filter is not used, but the order statistics filter ordfilt2)

主要运用MATLAB做了永磁同步电机的矢量控制仿真，改仿真系统全面(PMSM VC)

光伏低电压穿越的模型，效果不是比较理想，是大功率的，可在其上进行低电压控制策略的改进(PV LVRT model, the effect is not ideal, high-power, low-voltage control can be improved in its strategy on)
