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 linear eigensolver 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.
