Subsection 6.5.1 Systematic derivation of backward error analyses

Throughout the course, we have pointed out that the FLAME notation facilitates the systematic derivation of linear algebra algorithms. The papers

extend this to the systematic derivation of the backward error analysis of algorithms. Other publications and texts present error analyses on a case-by-case basis (much like we do in these materials) rather than as a systematic and comprehensive approach.
