This repository contains the code and results for the FMM translation operator experiments described in Appendix B of the paper A Fast Algorithm for Quadrature by Expansion in Three Dimensions (published here and also available on arXiv).
The following software is required:
- a Fortran compiler
- SciPy
- Pandas
- sumpy
To build the code, run ./build.sh, which compiles an auxiliary Python module
for evaluating associated Legendre functions. You can verify that the build
succeeded by running the tests in ./test_l3d.py.
The script ./translation_accuracy.py contains the accuracy experiments
described in the paper. Running this script generates a LaTeX report file. By
default, the script uses the saved data in the *.csv files and does not re-run
the experiments. To re-run the experiments, move/delete the saved *.csv data
first.
