EPSKrylovSchurGetSubintervals
Returns the points that delimit the subintervals used in spectrum slicing with several partitions.
Synopsis
#include "slepceps.h"
PetscErrorCode EPSKrylovSchurGetSubintervals(EPS eps,PetscReal **subint)
Not Collective
Input Parameter
| eps | - the eigenproblem solver context
|
Output Parameter
| subint | - array of real values specifying subintervals
|
Notes
If the user passed values with EPSKrylovSchurSetSubintervals(), then the
same values are returned. Otherwise, the values computed internally are
obtained.
This function is only available for spectrum slicing runs.
The returned array has length npart+1 (see EPSKrylovSchurGetPartitions())
and should be freed by the user.
Fortran Notes
The calling sequence from Fortran is
EPSKrylovSchurGetSubintervals(eps,subint,ierr)
double precision subint(npart+1) output
