EPSSetOperators

Sets the matrices associated with the eigenvalue problem.

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSSetOperators(EPS eps,Mat A,Mat B)
Collective on EPS and Mat

Input Parameters

eps - the eigenproblem solver context
A - the matrix associated with the eigensystem
B - the second matrix in the case of generalized eigenproblems

Notes

To specify a standard eigenproblem, use PETSC_NULL for parameter B.

It must be called after EPSSetUp(). If it is called again after EPSSetUp() then the EPS object is reset.
