#include "slepcnep.h" PetscErrorCode NEPRIISetLagPreconditioner(NEP nep,PetscInt lag)Logically Collective on NEP
| nep | - nonlinear eigenvalue solver | |
| lag | - 0 indicates NEVER rebuild, 1 means rebuild every time the Jacobian is computed within the nonlinear iteration, 2 means every second time the Jacobian is built, etc. |
| -nep_rii_lag_preconditioner <lag> | - Notes: The default is 1. The preconditioner is ALWAYS built in the first iteration of a nonlinear solve. |
