Abstract
A Schur-based factorization procedure is described for impedance matrices transformed into a localizing basis. A recently reported factorization strategy relying on a sparse QR factorization of the transformed impedance matrix was shown to exhibit improved efficiency relative to standard direct factorizations. It is shown here that a Schur factorization provides additional efficiencies.
