For cross-matching astronomical catalogs. Like np.intersect1d but faster.
From PyPI:
pip install fastxm
From source (requires maturin):
git clone https://github.com/al-jshen/fastxm
cd fastxm
maturin build --release
pip install target/release/<path to wheel>
from fastxm import intersect_1d
catalog_1 = ...
catalog_2 = ...
match_ix_1, match_ix_2 = intersect_1d(catalog_1['common_id'], catalog_2['common_id'], parallel=True)
This requires pytest and pytest-benchmark.
git clone https://github.com/al-jshen/fastxm
cd fastxm
maturin develop
