NEPInterpolSetInterpolation#

Sets the tolerance and maximum degree when building the interpolation polynomial.

Synopsis#

#include "slepcnep.h" 
PetscErrorCode NEPInterpolSetInterpolation(NEP nep,PetscReal tol,PetscInt deg)

Collective

Input Parameters#

  • nep - the nonlinear eigensolver context

  • tol - tolerance to stop computing polynomial coefficients

  • deg - maximum degree of interpolation

Options Database Keys#

  • -nep_interpol_interpolation_tol - Sets the tolerance to stop computing polynomial coefficients

  • -nep_interpol_interpolation_degree - Sets the maximum degree of interpolation

Note#

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.
