I tried to follow the numpy API as closely as I could, to see if something like this could work. The code isn't particularly optimized, but it does beat CSR/CSC spmatrix formats on a few benchmarks. My plan going forward is to have swappable (opaque) backends to allow for tradeoffs in speed/memory for access/construction/math operations.
Apologies for the lacking documentation! The only good listing of current capabilities at the moment is the test suite (https://github.com/perimosocordiae/sparray/tree/master/sparray/tests).
Wow, a great one from the Happy Valley! I've quite a bit of catching up to do --- you are miles ahead of me in terms of feature completeness. One difference I see is that you seem to be using a flat index. This likely does not play too well with assembly, which is what I tried to take into account. Would you be interested to join forces?
