hifir4py¶
| Release: | 0.1.0 |
|---|---|
| Date: | Aug 30, 2021 |
Introduction¶
hifir4py is the Python3 interface of the HIFIR (Hybrid Incomplete
Factorization with Iterative Refinement) preconditioner, which is originally
written in C++. HIFIR is desiable for preconditioning ill-conditioned
and (potentially) singular systems to seek least-squares and/or the
pseudoinverse solutions.
Installation¶
One can install hifir4py using pip, i.e.,
pip3 install hifir4py --user
In addition, refer to https://github.com/hifirworks/hifir4py/releases for archives of different versions.
For Windows users, we recommend using Windows Subsystem for Linux (WSL) or Cygwin.
Copyrights & Licenses¶
hifir4py is developed and maintained by the NumGeom Research Group at
Stony Brook University.
This software suite is released under a dual-license model. For academic users, individual users, or open-source software developers, you can use HIFIR under the AGPLv3+ license free of charge for research and evaluation purpose. For commercial users, separate commercial licenses are available through the Stony Brook University.
