些程序是一个雷达跟踪一目标的仿真图形,可实现kalman滤波的估计轨迹与真实轨迹的误差,并分别可绘出X,Y方向的跟踪误差,对初学都来说,是一个非常好的学习例子(These procedures is one goal of a radar tracking simulation graphics, can be realized kalman filter estimated trajectory with the true trajectory error, and can be mapped, respectively, X, Y direction of the tracking error for both novice, it is a very good learning examples)

采用bootstrap方法重抽样，可以将小样本变成大样本，适合乏信息问题(Resampling bootstrap method, small samples can be turned into a large sample suitable for lack of information problem)

《最优阵列处理_HarryL.VanTrees》非常经典的书籍，做阵列信号处理大家都知道！书中源代码！("The best array processing _HarryL.VanTrees" very classic books, do array signal processing everyone knows! The source code in the book!)

the clustering gives a high level of understanding with the present number of data sets which do not have a common behaviour between one and the other

KMV方法计算企业资产和资产波动率 参数说明： E:股权市值 D:负债总额 r：无风险利率 T:企业债期限 EquityTheta：股价波动率

说明：  这段代码详细描述了kl变换步骤及方法,谢谢下载(described in detail the steps and methods of Kl transform)
