Fast and Inverse-Free Algorithms for Deflating Subspaces

James Demmel, Ioana Dumitriu, Ryan Schneider

This paper explores a key question in numerical linear algebra: how can we compute projectors onto the deflating subspaces of a regular matrix pencil , in particular without…

Generalized Pseudospectral Shattering and Inverse-Free Matrix Pencil Diagonalization

James Demmel, Ioana Dumitriu, Ryan Schneider

We present a randomized, inverse-free algorithm for producing an approximate diagonalization of any matrix pencil . The bulk of the algorithm rests on a randomi…
