一篇讲解FDTD中，隐式格式迭代，总场散射场分离的改进的论文，对于学习总场散射场有重要作用。(FDTD in a brief, implicit iteration, the total field scattered field improved separation of papers, total field scattered field for the study has an important role.)

精通MATLAB计算科学书源代码，原书正版CD第三张源代码(Proficient in computer science book MATLAB source code, the third original CD to the book source code)

基于核方法的主成分分析matlab源代码，比较经典，推荐学习。(Method based on kernel principal component analysis matlab source code, more classic, recommended learning.)

floyd算法主要用于最小生成树，最短路径，把散点输进去，就可以生成最短路径(loyd algorithm is mainly used for minimum spanning tree, shortest path, the scatter lost in, you can generate the shortest path)

每个天线单元都由独立的移相开关控制，通过控制各天线单元发射的相位，就能合成不同相位波束。相控阵各天线单元发射的电磁波以干涉原理合成一个接近笔直的雷达主瓣，而旁瓣则是各天线单元的不均匀性而造成。(Each antenna unit is controlled by an independent phase shift switch. By controlling the phase transmitted by each antenna element, different phase beams can be synthesized. The electromagnetic wave emitted from each antenna unit of phased array generates a nearly straight radar main lobe based on the interference principle, while the sidelobe is caused by the heterogeneity of the antenna units.)

说明：  GDOP(Geometric Dilution of Precision) 几何精度因子是衡量一个定位系统精度的重要标准之一。 运行程序sGDOP.m可得到三站GDOP仿真结果，更改程序中s_x,y,z可以更改阵列的几何排列。运行程序fGDOP.m得到四站GDOP仿真结果。(GDOP (geometric division of precision) geometric accuracy factor is one of the important standards to measure the accuracy of a positioning system. Running the program sgdop. m, we can get the simulation results of three stations GDOP, and changing the geometry of the array by changing the program s _ x, y,z. Running the program fgdop.m, the simulation results of four stations GDOP are obtained.)
