PEPSTOARSetDimensions

Sets the dimensions used for each subsolve step in case of doing spectrum slicing for a computational interval. The meaning of the parameters is the same as in PEPSetDimensions().

Synopsis

#include "slepcpep.h" 
PetscErrorCode PEPSTOARSetDimensions(PEP pep,PetscInt nev,PetscInt ncv,PetscInt mpd)

Logically Collective

Input Parameters

	pep	- the eigenproblem solver context
	nev	- number of eigenvalues to compute
	ncv	- the maximum dimension of the subspace to be used by the subsolve
	mpd	- the maximum dimension allowed for the projected problem
