EdgeID = faceEdges(g,RegionID,FilterType)
returns internal, external, or all edges belonging to the faces with ID numbers listed in
RegionID. This syntax is valid for 3-D geometries only.
Face ID, specified as a positive number or a vector of positive numbers. Each number
represents a face ID.
Type of edges to return, specified as "internal",
"external", or "all". Depending on this
argument, faceEdges returns these types of faces for a 3-D
geometry:
"internal" — Edges belonging to only internal faces. Internal
faces are faces shared between multiple cells.
"external" — Edges belonging to only external faces. External
faces are faces not shared between multiple cells.
"all" — All edges belonging to the specified cells.
