Describe your change:

  • Fixed type hints in lu_decomposition.py to resolve mypy errors (see mypy produces errors when run on its own #8070)
  • Added explanation of LU decomposition
  • Added doctests to handle different cases in which an LU decomposition does or doesn't exist

Attempt 2 of making a PR since the first one (#8076) was closed due to having too many PRs open at a time.

  • Add an algorithm?
  • Fix a bug or typo in an existing algorithm?
  • Documentation change?

@cclauss Not sure why this still has the "tests are failing" label since it looks like all checks passed. Either way, does this look good to be merged?
