[SciPy-Dev] Willing to contribute to SciPy

[赵刚]

Dear SciPy team,

I have two questions when I read SciPy documents and source codes. 

1. In the directory "scipy/sparse/linalg/isolve/", I see the implementations of some sparse iterative solver and parameter interfaces with preconditioner, such as CG/PCG, BiCGSTAB/PBiCGSTAB, GMRES/PGMRES, FGMRES/PFGMRES, etc., it's great. But it seems that the detailed preconditioner has not been implemented currently (If multigrid preconditioners had been implemented, please let me know, thanks). So I'd like to ask if I can help you implement some Krylov methods by Multigrid preconditioned (the fastest preconditioner for SPD) to contribute to the SciPy community (From the perspective of necessity and value).

2. On the other hand, I would also like to know if the other parts of SciPy need me to do some improvements and enhancements. I am very willing to make a contribution to SciPy.


Best Wishes,
Gang Zhao
