PETSCSPACESUM#
“sum” - A PetscSpace object that encapsulates a sum of subspaces.
Note#
That sum can either be direct or a concatenation. For example if A and B are spaces each with 2 components, the direct sum of A and B will also have 2 components while the concatenated sum will have 4 components. In both cases A and B must be defined over the same number of variables.
