# 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()`
