# MatCreateSubMatrixOption
Indicates if matrices obtained from a call to `MatCreateSubMatrices()` include the matrix values. Currently it is only used by `MatGetSeqNonzeroStructure()`. 
## Synopsis
```
typedef enum {
  MAT_DO_NOT_GET_VALUES,
  MAT_GET_VALUES
} MatCreateSubMatrixOption;
```



## Values

- ***`MAT_DO_NOT_GET_VALUES` -*** do not copy the matrix values
- ***`MAT_GET_VALUES` -*** copy the matrix values



## Developer Note
Why is not just a boolean used for this information?
