Finite Element Toolbox Ver. 2.1 === === === === === = Date: 2002-04-01 Author: B. Rasmus Anthin. WHAT IS IT This is a toolbox for computing ODEs or PDEs in BVPs using FEM in 1D, 2D and 3D. * FEM1 this is the main routine for solving ODE BVPs using any combination of Dirichlet, Neumann or Robin conditions. * GENMAT1 called by FEM1 and is the core of the program. It generates the matrices used for solving the linear equation system for the ODE. * REFINE1 with this routine you can refine the mesh over certain critical grid points. The the gridpoints will become nonuniformly linearly spaced. * TEST1 this is a test for the 1D case of FEM. Look through this example carefully in order to fully understand how FEM1 works. * FEM2.mat contains examples over meshes/triangulations in 2D. * PLOTGRID2 plot mesh/triangulation in 2D and put a number in each corresponding element (triangle). * QUADSPACE generates
