Sparse Arrays?

[LMescheder]

Array fire includes limited sparse array functionality. Are there any plans to wrap these?

[pavanky]

af_matmul also supports sparse matrix, dense {matrix, vector} multiplications.

@LMescheder thanks for reporting this. Support for this will be included in ArrayFire.jl very soon.

[pavanky]

@ranjanan on a related note, there have been other functions added to arrayfire in 3.4.0:
https://github.com/arrayfire/arrayfire/releases/tag/v3.4.0

If it helps, I made the following issue when adding the necessary functionality to the python wrapper
arrayfire/arrayfire-python#100

[ranjanan]

@pavanky Thanks! This is very helpful.

[pavanky]

The names in the python wrapper are not identical, but they should provide as a template for the functions to be added.

[ranjanan]

@LMescheder I might not be able to get around to adding more functionality to this package for a few weeks. Would you mind putting together a PR to the package? That would be much appreciated. I would help and review as necessary. In general, more contributions to this package would be highly appreciated.

Has ArrayFire been updated to include sparse array constructors? I am looking to construct COO sparse arrays and solve a linear system Ax=b.

@bscohen1 You can use the sparse() function to create sparse matrices.
Other sparse handling functions can be found here.

Lastly, you can see sparse usage under the Conjugate Gradient example.

I was just wondering, if there is any update on wrapping the sparse functions of ArrayFire into julia code.

[ranjanan]

@lruthotto I have been a bit busy with a number of other things. But I think @GAIKA plans on including this functionality in his PR #121.

[lruthotto]

Thanks for the update! Looking forward to seeing this in action. @GAIKA let me know if you need someone to test this functionality. I don't think I can help much with writing the code, but this I can do.

@lruthotto - Can you write tests? I have all the wrappers for C code already in place (search for sparse in https://github.com/gaika/ArrayFire.jl/blob/master/src/wrap.jl ), it is just a matter of making sure all types match and maybe adjusting function signatures to be more Julian.

Thanks for @lruthotto's initiative and tests it is now possible to convert between AFArray and SparseMatrixCSC in #121
