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. Webb2 Polar decomposition of 3×3 matrices and quaternions We recall that a polar decomposition of a matrix A ∈ Rn×n is a factorization A = QH,whereQis orthogonal and H is symmetric positive semidefinite [13, Chap. 8]. Clearly, H = (ATA)1/2 is always unique, and when A is nonsingular H is positive definite and Q = AH−1 is unique.
Webbany eigencalculations, for computing the polar decomposition of a matrix in Sp(4,R) was provided in [2]. In physical applications where these groups arise, the positive definite factor in the polar decomposition can be interpreted as the “lossy” portion of such matrices, while the orthogonal factor is the conservative portion.
