PEPSetBasis

Specifies the type of polynomial basis used to describe the polynomial eigenvalue problem.

Synopsis

#include "slepcpep.h" 
PetscErrorCode PEPSetBasis(PEP pep,PEPBasis basis)
Logically Collective on pep

Input Parameters

pep  - the polynomial eigensolver context
basis  - the type of polynomial basis

Options Database Key

-pep_basis <basis>  - Select the basis type

Notes

By default, the coefficient matrices passed via PEPSetOperators() are expressed in the monomial basis, i.e. P(lambda) = A_0 + lambda*A_1 + lambda^2*A_2 + ... + lambda^d*A_d. Other polynomial bases may have better numerical behaviour, but the user must then pass the coefficient matrices accordingly.
