PEPSetOperators#
Sets the coefficient matrices associated with the polynomial eigenvalue problem.
Synopsis#
#include "slepcpep.h"
PetscErrorCode PEPSetOperators(PEP pep,PetscInt nmat,Mat A[])
Collective
Input Parameters#
pep - the eigenproblem solver context
nmat - number of matrices in array A
A - the array of matrices associated with the eigenproblem
Notes#
The polynomial eigenproblem is defined as P(l)x=0, where l is the eigenvalue, x is the eigenvector, and P(l) is defined as P(l) = A_0 + lA_1 + … + l^d*A_d, with d=nmat-1 (the degree of P). For non-monomial bases, this expression is different.
