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. Webb5 mars 2024 · 11.6: Polar decomposition.

WebbThe polar decomposition theorem therefore captures the elementary transformations, rotation and pure deformation, which make up F F and highlights the non-commutativity of the two transformations. Furthermore, if R = I R = I and therefore F = U = V F = U = V the transformation, in the point considered, it is a pure deformation.
