EPSIsStructured

Ask if the EPS object corresponds to a structured eigenvalue problem.

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSIsStructured(EPS eps,PetscBool* is)

Not Collective

Input Parameter

• eps - the linear eigensolver context

Output Parameter

• is - PETSC_TRUE if the problem is structured

Note

The result will be true if the problem type has been set to some structured type such as EPS_BSE. This is independent of whether the input matrix has been built with a certain structure with a helper function.
