Does Scipy Sparse use the (sparse) BLAS library?

Question

Numpy can use one of a number of BLAS libraries (eg. ATLAS, MKL, OpenBLAS etc.).

Does the scipy.sparse matrix module support the sparse BLAS library?

Answer 1

searching the scipy github for sparse BLAS produces a few files like

https://github.com/scipy/scipy/blob/6a4460f68315f0669604054be91ceeacd606f0b6/scipy/sparse/linalg/dsolve/SuperLU/README

This SuperLU solver is the only place where the two are mentioned together.
