进行Hilbert-Huang变换的源代码，可以对信号进行时频分析，非常好用

基于EKF的参数估计算法理论，这是个英文文献，主要介绍了用EKF方法去识别结构的参数。(The parameter estimation algorithm based on EKF theory, this is English literature, introduces the parameters EKF method to identify structures.)

说明：  一个多目标跟踪的matlab代码,里面附有说明文档.其中背景差分法可以实现实时更新.该代码在检测与跟踪少量目标时效果很好,但是跟踪目标大于8后,效果下降很多(A multi-target tracking matlab code, which accompanied by documentation. Including real-time background subtraction method can be updated. The code in small target detection and tracking works well, but the tracking target is greater than 8, the effect of decreased number of)

C++大作业，编写一个account类实现基类派生类之间的各种关系。主要用于初学者对于类的理解。(C++ big job, write a class that implements account the various relationships between the base class derived class. The main class for beginners to understand.)

ERA模态参数提取方法，根据特征参数提取(MOdal ERA method)

说明：  迹线法二维求轮轨接触点以及几何参数 ，输入轮廓面参数即可，里面有详细介绍。(The Geometrical Contact between Track and Wheelset)

基于Radon-Ambiguity变换和分数阶傅里叶变换的chirp信号检测及多参数估计(Based on Radon-Ambiguity Transform and Fractional Fourier transform of the chirp signal detection and multi-parameter estimation)

说明：  使用交叉熵算法，对组合优化问题，逐步逼近最优解完成寻优(Using cross entropy method to optimize the problem)
