Hi everyone,
Is there any other developments regarding this problem of linear algebra algorithms for sparse matrices ?
I think most of methods already implemented for instance in scipy or extensions such as scikit-sparse, are not yet implemented in Torch, for instance:

Sparse Cholesky decomposition, see e.g.  sksparse.cholmod

Solving linear systems Ax=b with A a sparse matrix
Product of two sparse matrices
…

It could be very useful to allow for automatic differentiation of such operations in Torch.
Thanks
