EPSSetType#

Selects the particular solver to be used in the EPS object.

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSSetType(EPS eps,EPSType type)

Logically Collective

Input Parameters#

eps - the linear eigensolver context
type - a known method

Options Database Key#

-eps_type - Sets the method; use -help for a list of available methods

Notes#

See EPSType for available methods. The default is EPSKRYLOVSCHUR.

Normally, it is best to use the EPSSetFromOptions() command and then set the EPS type from the options database rather than by using this routine. Using the options database provides the user with maximum flexibility in evaluating the different available methods. The EPSSetType() routine is provided for those situations where it is necessary to set the iterative solver independently of the command line or options database.
