MATLAB

附件中是国外测速雷达系统仿真的matlab程序，其中对雷达系统的仿真讲的比较透彻。(Annex is abroad matlab speed radar system simulation program, in which the radar system, a thorough comparison of the simulation stresses.)

AR自回归模型，主要介绍时间序列分析中重要的一个模型。(AR autoregression model, time series analysis introduces an important model.)

演示zeinike多项式拟合的源程序，开发环境为matlabR2006b(Polynomial fitting zeinike demo source, development environment for matlabR2006b)

求解Lambert问题。 输入：轨道上两个点的位矢R1、R2，以及从R1到R2所用的时间t(缺点是脉冲太大)。 输出：质点在R1端点的速度V1，质点在R2端点的速度V2. 此函数用于：在给定轨道上两个点的位矢R1、R2，以及从R1到R2所用的时间t。求解V1、V2。再调用前面的函数就可以确定轨道根数，及任意时刻质点的状态。(To solve the Lambert problem. Input: track two-point position vector R1, R2, and R1 to R2 used in the time t (The disadvantage is that the pulse is too large). Output: particle R1 endpoint speed V1, the particle in the R2 endpoint speed V2. This function is used: two points in a given orbit position vector R1, R2, and from R1 to R2 with the time t. Solve the V1 and V2. And then call the previous function can determine the orbital elements, and any moment of the particle' s state.)

matlab的图论工具箱，基本够用了，大家试一试。(matlab toolbox graph theory, basic enough, please try.)

J法解Poisson方程，通过迭代输出结果并画图，结果包含迭代步数以及无穷范数(Solution of Poisson equation by J method, iterative output results and drawing, the result contains iteration step number and infinite norm)

求点d1到直线d2-d3的距离，并画线。范例： [d dl]=find_dl([2 1],[8 3],[4 7]) 则 dl=[6 5]。(Example: [d dl] = find_dl ([2 1], [8 3], [4 7]) if dl = [6 5].)

kaihua-zhang的Fast Compressive Tracking的Matlab实现代码，对理解文章很有帮助。(The code of the paper Fast Compressive Tracking,Kaihua Zhang.)
