Synopsis#
MatMPIAIJGetSeqAIJF90(Mat A, Mat Ad, Mat Ao, {PetscInt, pointer :: colmap(:)},integer ierr)
Not Collective
Input Parameter#
A - the
MATMPIAIJ
matrix
Output Parameters#
Ad - the diagonal portion of the matrix
Ao - the off-diagonal portion of the matrix
colmap - An array mapping local column numbers of
Ao
to global column numbers of the parallel matrixierr - error code
Note#
Use MatMPIAIJRestoreSeqAIJF90()
when you no longer need access to the matrices and colmap
