EPSCISSGetKSPs#

Retrieve the array of linear solver objects associated with the CISS solver.

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSCISSGetKSPs(EPS eps,PetscInt *nsolve,KSP **ksp)

Not Collective

Input Parameter#

eps - the linear eigensolver context

Output Parameters#

nsolve - number of solver objects
ksp - array of linear solver object

Note#

The number of KSP solvers is equal to the number of integration points divided by the number of partitions, see EPSCISSSetSizes(). This value is halved in the case of real matrices with a region centered at the real axis.
