**triangulation_order1_display_test**,
a MATLAB code which
calls triangulation_order1_display(), which
makes a 3D plot of piecewise constant data defined on a mesh of triangles.

triangulation_order1_display, a MATLAB code which plots piecewise constant data associated with a triangulation;

- triangulation_order1_display_test.m, calls all the tests.
- triangulation_order1_display_test.sh, runs all the tests.
- triangulation_order1_display_test.txt, the output file.

**EXAMPLE1** is a set of node, element and value data.

- example1_nodes.txt, the coordinates of the nodes.
- example1_elements.txt, the indices of nodes that make the elements.
- example1_values.txt, the value associated with each element.
- example1.png, a PNG image of the MATLAB plot.

**EXAMPLE2** is a set of node, element and value data.

- example2_nodes.txt, the coordinates of the nodes.
- example2_elements.txt, the indices of nodes that make the elements.
- example2_values.txt, the value associated with each element.
- example2.png, a PNG image of the MATLAB plot.
