WebI could not figure out how; I got a big system of nonlinear equations when I tried by myself. That decomposition has 4 d.o.f. as does the original linear transform, which hints that if it's correct, then it's minimal (you can't do it with 2 rotations or 2 scalings, and you don't have enough d.o.f. with 1 rotation + 1 scaling).

WebJan 20, 2009 · In this article, we develop CUR matrix decompositions for improved data analysis.
