[WIP] CSR/ CSC Elemwise

4

Very WIP draft PR for elemwise operations on CSR and CSC arrays. Currently just implements broadcasting operations between compressed 2d arrays. Cases that would be covered by a full implementation:...

Support for DOK slicing and advanced indexing

9

Since the DOK array is versatile applicable I use them frequently in my projects. I needed support for slicing and advanced indexing and implemented it myself, see [gist](https://gist.github.com/stschroe/7c4660774835258c06b2be968eb49204#file-sparse_dok_indexer-py). The indexing...

use static arrays for indexing

6

I've replaced the dynamic structures with static ones for GCXS indexing. This improves the speed pretty significantly (twice as fast in a number of cases). Also, even allocating extra space...

Add CSD

33

`CSD` stands for Compressed Sparse Dimensions. It is a multidimensional generalization of `CSR`, `CSC` and `COO`. `CSD` has a few "compressed" dimensions and a few "uncompressed" dimensions. The "compressed" dimensions...

Support boolean indexing with a COO sparse matrix

While investigating https://github.com/theislab/scanpy/issues/921 I ran into the following limitation when using a boolean array as an index. This is the expected behaviour for regular NumPy: ```python >>> import numpy as...
