EPSKrylovSchurGetSubcommMats#

Gets the eigenproblem matrices stored internally in the subcommunicator to which the calling process belongs.

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSKrylovSchurGetSubcommMats(EPS eps,Mat *A,Mat *B)

Collective on the subcommunicator

Input Parameter#

  • eps - the eigenproblem solver context

Output Parameters#

  • A - the matrix associated with the eigensystem

  • B - the second matrix in the case of generalized eigenproblems

Notes#

This is the analog of EPSGetOperators(), but returns the matrices distributed differently (in the subcommunicator rather than in the parent communicator).

These matrices should not be modified by the user.
