STSetMatrices#
Sets the matrices associated with the eigenvalue problem.
Synopsis#
#include "slepcst.h"
PetscErrorCode STSetMatrices(ST st,PetscInt n,Mat A[])
Collective
Input Parameters#
st - the spectral transformation context
n - number of matrices in array
AA - the array of matrices associated with the eigensystem
Notes#
It must be called before STSetUp(). If it is called again after STSetUp() then
the ST object is reset.
In standard eigenproblems only one matrix is passed, while in generalized problems two matrices are provided. The number of matrices is larger in polynomial eigenproblems.
In normal usage, matrices are provided via the corresponding EPS of PEP
interface function.
