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

SIAM 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 ...

Matrix Algebras and Displacement Decompositions [PDF]

SIAM Journal on Matrix Analysis and Applications, 2000
This paper investigates classes of complex \(n\times n\) matrices for which there are formulae enabling computation of a matrix vector product \(Af\) by means of a small number of fast discrete transforms. The basic formula is the ``displacement formula'': \(A=\sum_{m=1}^{\alpha}L_{m}U_{m}\) where \(L_{m}\) and \(U_{m}\) are lower and upper triangular ...
