fem1d_bvp_linear_test, a C++ code which calls fem1d_bvp_linear() which applies the finite element method, with piecewise linear elements, to a two point boundary value problem in one spatial dimension, and compares the computed and exact solutions with the L2 and seminorm errors.

fem1d_bvp_linear, a C++ code which applies the finite element method (FEM), with piecewise linear elements, to a two point boundary value problem (BVP) in one spatial dimension, and compares the computed and exact solutions with the L2 and seminorm errors.
One of the tests makes convergence plots in the H1, L2 and Max norms.
