间断有限元
the structure of the DG-FEM is very similar to that of the finite element method (FEM), there are several fundamental differences. In particular,
the mass matrix is local rather than global and thus can be inverted at very
little cost, yielding a semidiscrete scheme that is explicit. Furthermore, by
carefully designing the numerical flux to reflect the underlying dynamics, one
has more flexibility than in the classic FEM to ensure stability for wavedominated problems. Compared with the FVM, the DG-FEM overcomes the
key limitation on achieving high-order accuracy on general grids by enabling
this through the local element-based basis

AGJDN
压缩包包含三个文件：
全主元高斯-约当消元法程序AGJDN.m；基于全主元高斯-约当消元法的迭代求解病态矩阵方法AGJDNM.m；AGJDN.m的测试方程。
程序参考自：Fortran常用算法程序集（第二版） 徐世良编。AGJDN.m能求解部分病态矩阵，而AGJDNM.m对于我的测试矩阵效果不佳，但也一并上传，仅供参考。
错漏之处，还望指正。
