triangulation_boundary_edges_test


triangulation_boundary_edges_test, a MATLAB code which calls triangulation_boundary_edges(), which analyzes the triangulation of a region, identify the edges that form the boundaries, organize the boundary edges into one or more connected components, and write a file describing the components and the sequence of boundary edges.

ELBOW is a curved region, looking like an elbow, that lies inside the unit square. It is triangulated using order 3 triangles. There are 320 nodes and 568 triangles. There are 66 nodes on the boundary.

ELL is an L-shaped region, using 96 triangles and 65 nodes. It is triangulated using order 3 triangles.

LAKE is an irregular lake-shaped region with an "island", which means the boundary is made of two components. It is triangulated using order 3 triangles.
