PetscErrorCode NEPInterpolSetInterpolation(NEP nep,PetscReal tol,PetscInt deg)

Collective

	nep	- nonlinear eigenvalue solver
	tol	- tolerance to stop computing polynomial coefficients
	deg	- maximum degree of interpolation

	-nep_interpol_interpolation_tol <tol>	- Sets the tolerance to stop computing polynomial coefficients
	-nep_interpol_interpolation_degree <degree>	- Sets the maximum degree of interpolation

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.
