# NEST: NEw Sparse maTrix dataset
NEST is a new sparse matrix dataset. Its purpose is to define a modern set of sparse matrices arising in relevant and actual scientific application in order to improve further sparse numerical methods. Nest can be seen as a continuity of the Sparse Matrix Market datasets and contain some curated sparse matrices from it as legacy references.

The matrices are stored as COO sparse matrices in `scipy.sparse.npz` archive format. Conversion utils to/from the matrix market format are provided.


## TODO:
### Quantum Transport
- [ ] Add OBC cell for `cnt_cp2k` as eigenvalue problem
- [ ] Add OBC cell for `cnt_w90` as eigenvalue problem
- [ ] Add OBC cell for `sinw_w90` as eigenvalue problem

### Device Modeling
- [ ] Add right-hand side for `kmc_potential_0`
- [ ] Add right-hand side for `kmc_potential_1`
