step background

step description prompt

Write a Python function to generate the distance matrix `distances` and pair indices `pair_idxs` from the given particle coordinates `configs` of shape (nparticles, 3). Return the distance vectors `distances` for each particle pair of shape (nparticles choose 2, 3) and `pair_idxs`, which is a list of pair indices.
