PEPJDSetMinimalityIndex#
Sets the maximum allowed value for the minimality index.
Synopsis#
#include "slepcpep.h"
PetscErrorCode PEPJDSetMinimalityIndex(PEP pep,PetscInt mmidx)
Logically Collective
Input Parameters#
pep - the polynomial eigensolver context
mmidx - maximum minimality index
Options Database Key#
-pep_jd_minimality_index <mmidx> - the minimality index value
Notes#
The default value is equal to the degree of the polynomial. A smaller value can be used if the wanted eigenvectors are known to be linearly independent.
Detailed information can be found at [Campos and Roman, 2020].
