#include "slepcnep.h" PetscErrorCode NEPSetSplitPreconditioner(NEP nep,PetscInt ntp,Mat P[],MatStructure strp)Collective on nep
nep | - the nonlinear eigensolver context | |
ntp | - number of terms in the split preconditioner | |
P | - array of matrices | |
strp | - structure flag for matrices |
The structure flag provides information about P_i's nonzero pattern in the same way as in NEPSetSplitOperator().
If the functions defining the preconditioner operator were different from the ones given in NEPSetSplitOperator(), then the split form cannot be used. Use the callback interface instead.
Use ntp=0 to reset a previously set split preconditioner.
