| MatPtAP() (with P of AIJ type) | - - MatSetLocalToGlobalMapping() |
| -mat_type is | - sets the matrix type to "is" during a call to MatSetFromOptions() | |
| -matis_fixempty | - Fixes local matrices in case of empty local rows/columns. | |
| -matis_storel2l | - stores the local-to-local operators generated by the Galerkin process of MatPtAP(). |
You must call MatSetLocalToGlobalMapping() before using this matrix type.
You can do matrix preallocation on the local matrix after you obtain it with MatISGetLocalMat(); otherwise, you could use MatISSetPreallocation()
