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

Not Collective

pep

- the polynomial eigensolver context

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

The user can specify NULL for any parameter that is not needed.
