Stable and efficient computation of generalized polar decompositions

Stable and efficient computation of generalized polar decompositions

We present methods for computing the generalized polar decomposition of a matrix based on the dynamically weighted Halley (DWH) iteration. This method is well established for computing the standard polar decomposition and a stable implementation is available, where matrix inversion is avoided and QR...
