Ask HN: How to solve sparse linear equation with Accelerate BLAS?

In an iOS app, I need to solve a linear equation Ax = B, where A is a sparse matrix with 40K rows and 10K columns.

Accelerate has a Sparse Solver package, but it is still in beta: https://developer.apple.com/documentation/accelerate/sparse_solvers

I wonder if I can use BLAS to solve the linear equation? BLAS contains functions to define a sparse matrix, but I don't see any solver functions.
