PetscErrorCode SVDPRIMMESetMethod(SVD svd,SVDPRIMMEMethod method)

Logically Collective

Input Parameters#

  • svd - the singular value solver context

  • method - method that will be used by PRIMME

Options Database Key#

  • -svd_primme_method <method> - sets the method for the PRIMME SVD solver

Notes#

If not set, the method defaults to SVD_PRIMME_HYBRID.
