 Blocks (CSB)` library. The library is written in `C/C++`, available at
 <https://people.eecs.berkeley.edu/~aydin/csb/html/index.html>. The
 library supports fast computation of large sparse matrix-vector

+products, $Ax$ and $A^{\rm T}x$ operations specifically, with sparse
 matrix $A$ in the format of compressed sparse blocks (CSB), on
