-
int HYPRE_SStructGraphDestroy(HYPRE_SStructGraph graph)
-
Destroy a graph object
-
int HYPRE_SStructGraphSetStencil(HYPRE_SStructGraph graph, int part, int var, HYPRE_SStructStencil stencil)
-
Set the stencil for a variable on a structured part of the grid
-
HYPRE_SStructGraphAddEntries
-
Add a non-stencil graph entry at a particular index
-
int HYPRE_SStructGraphAssemble(HYPRE_SStructGraph graph)
-
