MatSetFromOptions#
Creates a matrix where the type is determined from the options database.
Synopsis#
#include "petscmat.h"
PetscErrorCode MatSetFromOptions(Mat B)
Collective
Input Parameter#
B - the matrix
Options Database Keys#
-mat_type seqaij -
MATSEQAIJ
type, usesMatCreateSeqAIJ()
-mat_type mpiaij -
MATMPIAIJ
type, usesMatCreateAIJ()
-mat_type seqdense -
MATSEQDENSE
type, usesMatCreateSeqDense()
-mat_type mpidense -
MATMPIDENSE
, usesMatCreateDense()
-mat_type seqbaij -
MATSEQBAIJ
, usesMatCreateSeqBAIJ()
-mat_type mpibaij -
MATMPIBAIJ
, usesMatCreateBAIJ()
See the manpages for particular formats (e.g., MATSEQAIJ
)
for additional format-specific options.
Notes#
Generates a parallel MPI matrix if the communicator has more than one processor. The default
matrix type is MATAIJ
, using the routines MatCreateSeqAIJ()
and MatCreateAIJ()
if you
do not select a type in the options database.
