This package contains functions to rotate collections of 2D and 3D vectors.
Some of the functionality of this package is taken from the Halotools utilities sudmodule, reproduced here for convenience.
This package contains tools to perform:
- rotations of 3D vectors,
- rotations of 2D vectors,
- and monte carlo rotations of 2D and 3D vectors.
In order to use the functions in this package, you will need the following python packages installed:
- numpy
- astropy
Place this directory in your PYTHONPATH. The various functions can then be imported as, e.g.:
from rotations import rotate_vector_collection
or for 2- and 3-D specific functions,
from rotations.rotations3d import rotation_matrices_from_vectors
You can run the testing suite for this package using the pytest framework by executing the following command in the package directory:
pytest
