A Refined Harmonic Lanczos Bidiagonalization Method and an Implicitly Restarted Algorithm for Computing the Smallest Singular Triplets of Large Matrices
Zhongxiao Jia, Datian Niu
The harmonic Lanczos bidiagonalization method can be used to compute the smallest singular triplets of a large matrix . We prove that for good enough projection subspaces harmon…
