#include "slepceps.h" PetscErrorCode EPSCompareEigenvalues(EPS eps,PetscScalar ar,PetscScalar ai,PetscScalar br,PetscScalar bi,PetscInt *result)Not Collective
eps | - the eigensolver context | |
ar | - real part of the 1st eigenvalue | |
ai | - imaginary part of the 1st eigenvalue | |
br | - real part of the 2nd eigenvalue | |
bi | - imaginary part of the 2nd eigenvalue |
negative | - if the 1st eigenvalue is preferred to the 2st one | |
zero | - if both eigenvalues are equally preferred | |
positive | - if the 2st eigenvalue is preferred to the 1st one |
The criterion of comparison is related to the 'which' parameter set with EPSSetWhichEigenpairs().
