#include "petscmat.h" PetscErrorCode MatCreateRedundantMatrix(Mat mat,PetscInt nsubcomm,MPI_Comm subcomm,MatReuse reuse,Mat *matredundant)Collective on Mat Many br
mat | - the matrix Many br | |
nsubcomm | - the number of subcommunicators (= number of redundant parallel or sequential matrices) Many br | |
subcomm | - MPI communicator split from the communicator where mat resides in (or MPI_COMM_NULL if nsubcomm is used) Many br | |
reuse | - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX Many br |
This routine creates the duplicated matrices in subcommunicators; you should NOT create them before Many brcalling it. Many br
