Description: 一维伽辽金型无网格法MATLAB程序
无网格方法采用基于点的近似，可以彻底或部分地消除网格，不需要网格的初始划分和重构，不仅可以保证计算的精度，而且可以大大减小计算的难度。然而，由于目前的无网格近似一般没有解析表达式，且大都基于伽辽金原理，因此计算量很大，要超出传统的有限元法；另外，无网格近似大都是拟合，因此对于位移边界的处理比较困难，多采用拉格朗日乘子法处理。-1维伽Galerkin-type meshless method MATLAB procedures meshless method based on the point of approximation, can be completely or partially eliminate the grid, the grid does not require the initial division and reconstruction, not only can guarantee the accuracy of the calculation, and can greatly reduce the difficulty of calculation. However, due to the current meshless approximation there is no analytic expression in general, and mostly based on the Galerkin principle, the calculation of a large volume, it is necessary to go beyond the traditional finite element method In addition, the meshless approximation are fitted, so displacement of the border more difficult to deal with, the use of Lagrange law.

Description: 介绍用matlab进行有限元计算的国外经典著作，前面重点介绍了有限元的相关内容，后面重点讲解了如何利用matlab的工具箱实现有限元的计算。-This book gives a background treatment of the Galerkin method in Chaps. 2–4.
Topics such as developing weak formulations as prelude to solving the finite
element equation, interpolation functions, derivation of elemental equations,
assembly and sample solutions were treated in these chapters. Chapter 5 gives an
overview on the use of the pdetoolbox. Chapter 6 and 7 give different sample
problems and their solutions on heat transfer and elasticity in Materials
