# MATHYPRESTRUCT
MATHYPRESTRUCT = "hyprestruct" - A matrix type to be used for parallel sparse matrices based on the hypre HYPRE_StructMatrix. 


## Notes
Unlike the more general support for blocks in hypre this allows only one block per process and requires the block
be defined by a `DMDA`.

The matrix needs a `DMDA` associated with it by either a call to `MatSetDM()` or if the matrix is obtained from `DMCreateMatrix()`


## See Also
 `MatCreate()`, `PCPFMG`, `MatSetDM()`, `DMCreateMatrix()`

## Level
intermediate
