PEPSetOperators
Sets the coefficient matrices associated with the polynomial eigenvalue problem.
Synopsis
#include "slepcpep.h"
PetscErrorCode PEPSetOperators(PEP pep,PetscInt nmat,Mat A[])
Collective on PEP and Mat
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 + l*A_1 + ... + l^d*A_d, with d=nmat-1 (the degree of P).
For non-monomial bases, this expression is different.
