Constructor for the original side.
- Parameters:
-
| m_ | The matrix whose sparsity pattern is communicated. |
| idxset_ | The index set corresponding to the local matrix. |
| aggidxset_ | The index set corresponding to the redistributed matrix. |
template<class M , class I >
Constructor for the redistruted side.
- Parameters:
-
| m_ | The matrix whose sparsity pattern is communicated. |
| idxset_ | The index set corresponding to the local matrix. |
| aggidxset_ | The index set corresponding to the redistributed matrix. |
| rowsize_ | The row size for the redistributed owner rows. |
Member Function Documentation
template<class M , class I >
Completes the sparsity pattern of the redistributed matrix with data from copy rows for the novlp case.
After the pattern communication this function can be used.
- Parameters:
-
| add_sparsity | Sparsity pattern from the copy rows. |
