Creates a preconditioner context.

Synopsis

#include "petscksp.h" 
PetscErrorCode  PCCreate(MPI_Comm comm,PC *newpc)
Collective on MPI_Comm

Input Parameter

comm -MPI communicator

Output Parameter

pc -location to put the preconditioner context

Notes

The default preconditioner for sparse matrices is PCILU or PCICC with 0 fill on one process and block Jacobi with PCILU or ICC in parallel. For dense matrices it is always PCNONE.

Keywords

PC, create, context
