This directory provides the code for the experiments
to the paper
"Adaptive meshfree approximation for linear
elliptic partial differential equations with
PDE-greedy kernel methods" by
Tizian Wenzel, Daniel Winkle, Gabriele Santin, and Bernard Haasdonk

More specific:

For reproducing the FEM convergence table on the sector example
of Section 6.1, please

a) Install RBmatlab from the website www.morepas.org/software

The code can be run if RBmatlab from version 16.09 is installed

b) run the script fem_sector_example.m from this directory

Caution:

This operation is very expensive (takes several hours) as hundred of
thousands of point with global coordinates need to be searched and found
in FEM meshes. This is required to be consistent in the error computation
to other approximation techniques using these uniform test grids.
