## How to use this PAD

1. List the projects you would like to work on
2. Choose one, in the list, and mark your initials (e.g. [CP]) before it, cut and paste the line in the Work in progress section
3. Once the work is done, cut and paste it to the Needs review or Done sections.

## List of projects

- [Name of large examples directory FRAMACALC](https://lite.framacalc.org/9dxl-ujs4yd0xl5)
- [JGD] [LinBox PR#230](https://github.com/linbox-team/linbox/pull/230) Multimodular lifting container
- HPAC DLP: passer en production dans LinBox le code ad-hoc du DLP HPAC
- Site web linalg.org

- polynomial matrix:
-- Zhou-Labahn-Storjohann kernel basis algorithm
-- determinant algorithm
- [VN] finalize branch "approx-basis", containing minor improvements of approximant basis algorithms (délayé for the moment, waiting for new polmats)
-- see if some ideas from PML can help
-- review algorithms and compare speed with existing PM-Basis
-- extensive tests (rank-deficient, strange shifts...)
- [fflas-#288](https://github.com/linbox-team/fflas-ffpack/issues/184): fix charpoly checker over ZRing<Integer>
## Work in Progress
- [VN] working on prototype of kernel basis algo (simple version, based on high order approx)
- [CB] Fixing branch FFT_modular_double in case where AVX is present but not AVX2 (hpac)
- update use of maxFFLASCardinality in fflas
- [PG] improve polynomial matrix representation
