Structural Convergence Results for Approximation of Dominant Subspaces from Block Krylov Spaces

Petros Drineas, Ilse Ipsen, Eugenia-Maria Kontopoulou +1

This paper is concerned with approximating the dominant left singular vector space of a real matrix of arbitrary dimension, from block Krylov spaces generated by the matrix $AA…

Randomized Matrix-free Trace and Log-Determinant Estimators

Arvind K. Saibaba, Alen Alexanderian, Ilse C. F. Ipsen

We present randomized algorithms for estimating the trace and deter- minant of Hermitian positive semi-definite matrices. The algorithms are based on subspace iteration, and access…
