Linear discriminant analysis (LDA) and the related Fisher s linear discriminant are methods used in statistics, pattern recognition and machine learning to find a linear combination of features which characterizes or separates two or more classes of objects or events. The resulting combination may be used as a linear classifier, or, more commonly, for dimensionality reduction before later classification.

用于检测微弱信号的Duffing系统，这是我的毕业设计一部分，因为我做的时候也曾求取过很多资料，但是并没有找到，因此在我完成之后，上传这个代码，希望这个能帮助别人。 里面还有后续做的GUI界面实现的Duffing振子检测功能，可检测信号幅值和频率。(The Duffing system for detecting weak signals, this is part of my graduation project, because I also asked for a lot of information when I did it, but it was not found, so after I finished, upload this code, I hope this can help others.)

虚拟同步机的并网simulink模型，主要是VF+DROOP CONTROL的结合，解决了虚拟阻抗的加入(Virtual machine synchronization and network simulink model is mainly a combination VF+DROOP CONTROL solve the virtual impedance added)

本程序主要是针对一九杆结构进行的动力学分析，用newmark法，威尔逊法，状态空间法，子空间迭代法等求解了结构动态响应，并给出了图像显示(This program is mainly aimed at the structure of the 19 dynamic analysis, using newmark method, Wilson law, the state space method, subspace iteration method for solving the structural dynamic response, etc., and gives the image display)
