# MatSeqAIJHIPSPARSEGetIJ
returns the device row storage i and j indices for MATSEQAIJHIPSPARSE matrices. Not collective 
## Synopsis
```
#include "petscmat.h" 
PetscErrorCode MatSeqAIJHIPSPARSEGetIJ(Mat A, PetscBool compressed, const int **i, const int **j)
```

## Input Parameters

- ***A -*** the matrix
- ***compressed -*** PETSC_TRUE or PETSC_FALSE indicating the matrix data structure should be always returned in compressed form



## Output Parameters

- ***ia -*** the CSR row pointers
- ***ja -*** the CSR column indices





## Notes
When compressed is true, the CSR structure does not contain empty rows
