Factorization? #363

Closed Sentient07 closed 3 weeks ago

Sentient07 commented 7 months ago

Hi,

I was wondering if you'd provide LU/Cholesky/QR factorization for sparse matrices? https://github.com/rgl-epfl/cholespy library provides for cholesky but one would need PD matrices. If I'd want to do LU, I still have to do to_dense() and use torch.lu() which isn't optimal. Hence, was wondering if it could be done using pytorch_sparse? Thanks!

Thanks for the issue. We currently don't have any plans to support such operations in our library.
