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
