Computing the Polar Decomposition and the Matrix Sign Decomposition in Matrix Groups [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2004
The polar decomposition of \(A\) is \(A=UH\), where \(A\) has complex elements, \(U\) is unitary, \(H\) is Hermitian positive semi-definite. The authors identify a family of globally convergent rational iterations that preserve group structure. They show how the structure preservation leads to particularly convenient convergence tests in the case of ...
