线性调频信号是一种雷达常用的电磁波信号

matlab的pde工具箱很薄弱，同时只能处理有限复杂度的问题，利用comsol强大的有限元分析与多物理场的耦合性，解决相当完美。 matlab与多物理场有限元软件的结合，本程序需要安装matlab7.0以上以及comsol multiphysics 3.0以上版本，建立客户端后可以方便的利用matlab控制有限元软件，进行建模计算。 本程序描述的是点电荷周围的电场以及电势。适合于初学者(The pde matlab toolbox is very weak, and can only handle a limited complexity of the problem, by using comsol powerful finite element analysis and multi-physical field coupling to solve quite perfect. matlab and multi-physics finite element software combination, the above procedure to install matlab7.0 and comsol multiphysics 3.0 or later, after establishing the client can easily control the use of matlab finite element software to model calculations. This procedure describes the electric field around a point charge and the electric potential. Suitable for beginners)

说明：  均匀组织的光场分布，光源和检测器的方向只能竖直向下(Uniform tissue distribution of light, the direction of the light source and detector can only be straight down)

反步法求取船舶的运行轨迹，是大连海事大学某学生毕业论文中的仿真图形。(Backstepping strike a ship running track, Dalian Maritime University, a student thesis in the simulation graphics.)

该函数实现的是激光光斑中心检测。首先对光斑进行预处理，然后利用灰度重心法来计算得到光斑的中心坐标,最后利用MATLAB的绘图功能描绘出光斑中心位置的变化情况。(This function is implemented in the laser spot detection. First spot pretreatment, and then use the barycenter method to calculate the coordinates of the center of the spot, the final use of MATLAB graphics depict the changes in the spot center position.)

Here we have modelled a five-phase induction motor and we have applied DTC control technique to the machine
