有限元平面应力问题计算，总体刚度矩阵矩阵压缩存储，LU分解求解(Plane stress finite element calculation, the overall stiffness matrix of compressed storage matrix, LU decomposition Solving)

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.)
