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

Notes#

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