I feel like they (and everyone else) should just use SuiteSparse: http://faculty.cse.tamu.edu/davis/suitesparse.html

In the same way that people almost universally use BLAS and LAPACK or the MKL for linear algebra.

While there is a "suitesparse-5.2.0" package in conda, I haven't found any documentation. Do you have a link? There doesn't seem to be anything on the project website. I wasn't even quite sure this contains a Python package.

I suspect it's not. The code is largely written in C and C++ and what I can see of the package on Github makes it look like it's the version of SuiteSparse with CMake as the build system.

I realise my comment may have come off a bit flippant - it wouldn't be a trivial piece of work to write Python bindings for SuiteSparse, but would conceivably be simpler than trying to write a better sparse matrix algebra implementation.
