Implicitly restarted arnoldi
WitrynaAn Implicitly Restarted Arnoldi Method (IRAM) is used in the former case and an Implicitly Restarted Lanczos Method (IRLM) in the latter.

WitrynaReverse communication interface for the Implicitly Restarted Arnoldi Iteration. For symmetric problems this reduces to a variant of the Lanczos method. This method has been designed to compute approximations to a few eigenpairs of a linear operator OP that is real and symmetric with respect to a real positive semi-definite symmetric …
