vertex_to_dof_map

dolfin.cpp.fem.vertex_to_dof_map()

Return a map between vertex indices and dof indices Only works for FunctionSpace with dofs exclusively on vertices. For mixed FunctionSpaces dof index is offset with the number of dofs per vertex.

Parameters:FunctionSpace & space (const) – (FunctionSpace ) The FunctionSpace for what the vertex to dof map should be computed for Return type:std::vector< dolfin::la_index > Returns:std::vector<dolfin::la_index> The vertex to dof map
