With respect to the in uence on the development and practice of In this lecture, we discuss iterative methods based on Krylov subspace projection for extracting a few eigenvalues and eigenvectors of a large sparse matrix. F. RomaniIntroduction. Following convention, I will write Kj for that subspace Abstract—Krylov subspace methods have had an unparalleled success in solving real-life problems across disciplines ranging from computational fluid dynamics to statistics, What is a Krylov subspace method? ContentsIntroductionKrylov methodsWhy use Krylov methods Krylov subspace methods for solving linear systems. Classical meth-ods that do not belong to this class, like the successive overrelaxation (SOR) method, are no longer competitive In this lecture, we discuss iterative methods based on Krylov subspace projection for extracting a few eigenvalues and eigenvectors of a large sparse matrix.
