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
