这是我另一个同学的关于图像处理与机器学习的作业，对四组图像提取特征值，进行分类识别。LIBSVM.文件里包含代码，及一些参数调试。(This is another of my classmates on image processing and machine learning operations on four sets of image feature extraction values ​ ​ for classification. LIBSVM. File contains the code, and some parameters debugging.)

I think this file can be used to filter the latent state variable(used to filter the latent state variable)

该程序模拟了经典双稳系统随机共振中，噪声强度与系统做功的关系(The program simulates the classical stochastic resonance in bistable system, the relationship between noise intensity and the system to do work)

四阶龙格库塔法的一个实例 希望能够帮助大家(Fourth-order Runge-Kutta method)

机械工艺系统设计，基于VB进行了开发，该窗体重点是 参数的输入窗口(Mechanical process system design, based on the VB carried out the development, the focus on form parameters input window)
