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
