Support for CSRMatrix
I am currently working on code that computes matrix-matrix products of large, sparse matrices (>1k rows/columns, similar number of non-zero entries), which is relatively slow (multiple hours per product). I assume that this could be computed much faster by storing these matrices in a sparse representation and computing the products using respective sparse routines. However, I could not find any support for the sparse matrix class CSRMatrix in this wrapper.
Is this already implemented and I simply did not look in the right place? Are there any plans to support CSRMatrix in this wrapper in the near future?
You're right that it is not yet exposed in this python wrapper. I believe it's simply due to no one having had the time / need for it up till now.
Do I correctly understand that implementation would simply require replicating https://github.com/symengine/symengine.py/blob/5496ffcb4d9d24ee4af2754aafc124c5fc0e21c5/symengine/lib/symengine.pxd#L793 and following and adapting it to the CSRMatrix class?
Yes, together with the corresponding adaptions in symengine_wrapper.pyx and adding a few tests to the test suite.
