Software

    A C++ software package in C++ for solving the Poisson's equation on a polygonal domain (possible with cracks) using first order polynomials on graded meshes. This package provides optimal rates of convergence even in the case of concave domains (reentrant corners).

    A MATLAB software package for solving the Poisson's equation on a smooth domains using the Generalized Finite Element Method. Use the program solution.m (to run type solution(n), where n is the level of refinement).
