#include "slepcpep.h" PetscErrorCode PEPSetInterval(PEP pep,PetscReal inta,PetscReal intb)Logically Collective on pep
pep | - eigensolver context | |
inta | - left end of the interval | |
intb | - right end of the interval |
-pep_interval <a,b> | - set [a,b] as the interval of interest |
In the command-line option, two values must be provided. For an open interval, one can give an infinite, e.g., -pep_interval 1.0,inf or -pep_interval -inf,1.0. An open interval in the programmatic interface can be specified with PETSC_MAX_REAL and -PETSC_MAX_REAL.
