**triangle_display_test**,
a MATLAB program which
calls triangle_display() to plot a triangulation using files associated with
Jonathan Shewchuk's triangle() program.

triangle_display, a MATLAB program which displays the nodes and elements of a triangulation on the MATLAB graphics screen, assuming the data has been stored in NODE and ELE files by Jonathan Shewchuck's triangle() program.

- triangle_display_test.m, calls all the tests.
- triangle_display_test.sh, runs all the tests.
- triangle_display_test.txt, the output file.

**GREENLAND** is a triangulation of Greenland, using
a graded (varying-size) mesh of 33,343 nodes and 64,125 nodes.
The resulting image is essentially a red blob the shape of Greenland.
However, using the ZOOM tool, it is possible to see interesting
details of the mesh.

- greenland.node, the nodes;
- greenland.ele, the elements;
- greenland_zoom.png, a zoomed image of the upper right margin of the triangulation.

**SQUARE_CIRCLE_HOLE.1** is a square region with a circular hole.
826 nodes and 1517 elements are used.

- square_circle_hole.1.node, the nodes;
- square_circle_hole.1.ele, the elements;
- square_circle_hole.1.png, an image of the triangulation.
