求解Chen系统的最大lyapunov指数。求解方法为定义法。两条相轨线的步长为初设距离d0的基础上加上相对分量。求解时直接运行chen_lyapunov.m即可。可移植性强，比如换求其他系统的最大lyapunov指数，只需要改变变量数目，方程即可。(Solving the maximum lyapunov index Chen system. Solving method for defining method. Plus the relative weight of the two basic steps of the phase trajectories for the preliminary design of the distance d0. Can be run directly chen_lyapunov.m solving. Portability, such as changing the index for the largest lyapunov other systems, you only need to change the number of variables, the equation can be.)

雷达数据处理对于观测的目标位置数据（称为点迹）进行滤波处理，自动形成航迹，并且可以对下一个目标的位置进行估计预测。利用最小二乘算法（LMS）进行滤波处理，得到了比较稳定的航迹估计。 最小二乘方法是参数估计中一种较为常见的参数估计方法。对于雷达观测数据，在我们假定已经精确知道航迹的运动学模型之后，通过建立观测方程，即可以对于模型的参数，如初速度，初始位置和加速度等进行最小均方误差估计。采用序贯最小二乘的方法可以对观测数据进行实时处理，已对待估计参数进行实时更新，然后利用观测模型可以对 数据进行滤波计算。(Radar data processing for target position data observed (known as trace points) filter processing, automatic track, and can be estimated to predict the position of the next target. Using the least squares algorithm (LMS) filtering process, have been relatively stable track estimates. Least-squares parameter estimation method is a more common parameter estimation method. For radar data, we assume that the kinematic model has been accurately track after, through the establishment of observation equations, which can be the parameters of the model, as ever speed, acceleration, etc. initial position and minimum mean square error estimation. Sequential least squares method using the observed data can be processed in real time, has been to treat the estimated parameters are updated in real time, and then use observational data can be filtered model calculations.)
