Hi all,

Matt Haberland and I are happy to open PR gh-14433 to close the long-standing issue gh-857 through PROPACK integration into scipy.sparse.linalg.svds based on the previous work done by @jakevdp in pypropack.

This PR includes:

- PROPACK wrappers exposing a new 'propack' solver backend for scipy.sparse.linalg.svds

- an overhaul and expansion of the scipy.sparse.linalg.svds test suite, documentation, and benchmarks

- inclusion of a new PROPACK submodule under the SciPy organization which includes patches for known bugs, Fortran compiler support, and OpenMP issues

Thanks,

Nicholas
