The polar decomposition
Webb30. Lecture 30: 8.3 Polar Decomposition and Singular Value Decomposition In the book the singular value decomposition is proven in detail and the polar decomposition is only outlined in the exercises. One can prove one from the other in any order. Here we rst prove the polar decomposition since it is more natural though the proof is more abstract. Webb9 aug. 2016 · The polar decomposition of a dense matrix is an important operation in linear algebra. It can be directly calculated through the singular value decomposition (SVD) or iteratively using the QR...
