José Eduardo Chiarelli Bueno Filho requested to merge eduardo.bueno/dune-istl:spqr-lsq into master Sep 15, 2022

This merge request makes two additions:

Fix a segfault that was happening when calling SPQR for solving least squares problems
Adapts SPQR to work with blocked (BCRS) matrices and right hand sides composed of vectors with matrix-valued entries
