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…
