ppc_poisson, a C code which solves the 1 dimensional Poisson equation as a boundary value problem (BVP), using triangle() for the mesh, the finite element method (FEM) for discretization, umfpack() to solve the linear system, and geomview() for visualization, from Rouben Rostamian's "Programming Projects in C";
