说明：  用MATLAB解偏微分方程。讨论了以 中偏徽分方程工具箱的用法 用这个工具箱解方程的过程是 确定待解的偏徽分 方程 确定边界条件 确定方程所在城 的几何形状 划分有限元 解方程
(Solution of partial differential equations with MATLAB. Discussed in the partial differential equation toolbox emblem with the use of this toolbox is the process of solving equations to be solved to determine the emblem of the partial differential equations boundary conditions to determine the geometry of the city where the equations into the finite element solution of equation)
