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[]) PeNS
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
