EPSEVSLSetPolParameters

Defines the parameters used for building the building the polynomial in the EVSL solver.

#include "slepceps.h" 
PetscErrorCode EPSEVSLSetPolParameters(EPS eps,PetscInt max_deg,PetscReal thresh)

Logically Collective

	eps	- the eigensolver context
	max_deg	- maximum degree allowed for the polynomial
	thresh	- threshold for accepting polynomial

	-eps_evsl_pol_max_deg <d>	- set maximum polynomial degree
	-eps_evsl_pol_thresh <t>	- set the threshold

PETSC_CURRENT can be used to preserve the current value of any of the arguments, and PETSC_DETERMINE to set them to a default value.
