刚开始学习编码，希望能够和各位多多交流。也希望这个小程序能够抛砖引玉。(Has just started to learn coding, and you want to interact more. Also hope that this small program can attract valuable comments.)

数值分析中的最小二乘法应用面广，简单实用，也可以应用到工程实际中去(Numerical analysis of a wide range of application of the least square method is simple and practical, but also can be applied to engineering practice to)

使用matlab实现有限元方法求解各种问题。(Calculated using the finite element method using matlab.)

Implement the K nearest neighbor algorithm by your own instead of using available software. 2. Use K-fold cross validation to generate training and testing datasets. You should try different K values (3~8) to see how they affect your result. 3. Train the classifier using your training dataset, and test the classifier using your testing dataset. 4. Repeat the experiment (Step 2 and Step 3) 30 times. For each time, you need to record the training data accuracy and testing data accuracy. Finally, you can obtain the average training data accuracy and average testing data accuracy.
