Least Squares, Projections, and Pseudoinverses

These papers form a small sample of Stewart’s work on least squares, projec- 14 tions, and generalized inverses; see also [GWS-J23, GWS-J28, GWS-J60, GWS-J97, 15 GWS-J119, GWS-N5, GWS-N24], for example. Stewart’s focus in this area was to 16 put the understanding of generalized inverses on as firm a footing as that of the 17 usual matrix inverse. He proceeded by establishing continuity properties, effects of 18 scaling, and perturbation theory, using orthogonal projectors as a unifying frame- 19 work. 20 These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
