NEPCISSGetKSPs

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

Synopsis

#include "slepcnep.h" 
PetscErrorCode NEPCISSGetKSPs(NEP nep,PetscInt *nsolve,KSP **ksp)

Collective

Input Parameter

• nep - the nonlinear 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.
