# MatMPIAIJGetSeqAIJF90
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`
