EPSKrylovSchurSetSubintervals
Sets the points that delimit the subintervals to be used in spectrum slicing with several partitions.
Synopsis
#include "slepceps.h"
PetscErrorCode EPSKrylovSchurSetSubintervals(EPS eps,PetscReal subint[])
Logically Collective
Input Parameters
| eps | - the eigenproblem solver context
|
| subint | - array of real values specifying subintervals
|
Notes
This function must be called after EPSKrylovSchurSetPartitions(). For npart
partitions, the argument subint must contain npart+1 real values sorted in
ascending order, subint_0, subint_1, ..., subint_npart, where the first
and last values must coincide with the interval endpoints set with
EPSSetInterval().
The subintervals are then defined by two consecutive points [subint_0,subint_1],
[subint_1,subint_2], and so on.
