我们将建立一个类似iFEM的包或具有某些扩展的简化版本，称为mFEM工具箱。 fem：它包括各种源代码。 示例：所有与有限元和变分对应的示例都放在示例文件夹中。 工具：您可以找到涉及可视化、边界设置、网格生成和数值积分等功能。 pdedata：它提供了与示例文件夹中的示例相关联的方程的信息。 meshdata：它讲述了各种示例中使用的网格数据。 matlabupdate：更新版本的matlab中的一些函数是用相同的输入和输出重构的。例如，包含.m--->分枝杆菌.m。 多边形网格的显示和标记 我们提出了一些显示多边形网格的基本函数，包括节点、元素和（边界）边的标记。 辅助网格数据和setboundary.m 为了便于计算，我们引入了一些辅助网格数据。这个想法源于iFEM中对三角测量的处理，该处理被推广到经过某些修改的多边形网格。 FEM1D.m和main_FEM1D.m介绍了一维问题的有限元程序设计。详细说明了刚度矩阵和载荷矢量的组合。 给出了求解二维泊松方程的源代码，见Poisson.m、PoissonP2.m和PoissonP3.m。 对于线性弹性问题，我们给出了一个统一的规划框架
