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.
