Returns the local pieces of this distributed matrix

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 matrix

• ierr - error code

Note

Use MatMPIAIJRestoreSeqAIJF90() when you no longer need access to the matrices and colmap
