Matrix Computations and Scientific Computing Seminar: Fiedler and almost-tridiagonal matrices

Seminar | February 8 | 11 a.m.-12 p.m. | 380 Soda Hall

We begin with Fiedler's 2003 paper in which he introduced his new 5-diagonal companion matrix. Then we review a few diverse topics that introduce special interesting matrices: CMV,banded with banded inverse, and quasi-separable. We show the connecting link and note that all of the forms are invariant under the LR transform.
