Černý, A. (2009). Characterization of the oblique projector U(VU)V-dagger with application to constrained least squares. Linear Algebra and its Applications, 431(9), pp. 1564-1570. doi: 10.1016/j.laa.2009.05.025
Abstract
We provide a full characterization of the oblique projector U(VU) †V in the general case where the range of U and the null space of V are not complementary subspaces. We discuss the new result in the context of constrained least squares minimization which finds many applications in engineering and statistics.
