Custom[Matrix|Vector] equivalent for sparse types?

[Hartmut Kaiser]

Is there an equivalent type like CustomMatrix but for sparse data types (like CompressedMatrix)? Or even better if there were something similar allowing to abstract arbitrary (dense and sparse) types...

Thanks!

Hi Hartmut!

Thanks a lot for creating this issue. Unfortunately there is no equivalent to CustomMatrix for sparse matrices yet. However, for a long time we have planned to add a sparse matrix data structure for classical compressed row storage (CRS) and compressed column storage (CCS) matrices. We believe that it could be feasible to implement this data structure such that it would resemble the functionality of CustomMatrix. We will definitely keep this great idea in mind, thanks again,

Best regards,

Klaus!

Thanks for you prompt reply, Klaus. What can we do to help here? We definitely could spare some resources, but I think we would need some guidance on how you'd like to have it implemented and how this would fit best into the existing infrastructure.

Thanks for the offer. The current goal is to release Blaze 3.4 till the end of August, but after that we will hopefully have some time to think ahead and consider this details for this issue. Let me get back to you once Blaze 3.4 is finished. Thanks again!
