四阶龙格库塔法 数值计算 C++源码 可直接运行(Fourth-order Runge-Kutta numerical method C++ source code can be run directly)

本程序用于电力系统不对称故障计算，matlab实现，希望有所帮助(This procedure for the asymmetry of power system fault calculation, matlab realize the hope that help)

利用Python实现特征的MinMax标准化和Z-Score标准化两种特征归一化方法。并用原特征、两种归一化特征分别进行朴素贝叶斯模型训练，比较模型性能。(Two normalization methods of MinMax normalization and Z-Score standardization are implemented by Python. The naive Bayes model is trained with the original features and two normalization features respectively to compare the performance of the model.)
