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 on EPS

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.
