**triangulation_boundary**,
an Octave code which
starts with a triangulation of a simple shape, and
determines the triangle edges that form the boundary,
and a sequence of nodes that trace the boundary.

The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.

**triangulation_boundary** is available in
a MATLAB version and
an Octave version.

- boundary_edge_to_path.m, constructs a path of nodes around a triangulation.
- node_to_ij.m, converts a node index to parallelogram IJ coordinates.
- timestamp.m, prints the YMDHMS date as a timestamp.
- triangulation_ijk_to_node.m, returns the indices of triangle vertices.
- triangulation_node_to_boundary_edge.m, returns triangulation boundary edges.
