**triangulation_node_to_element_test**,
a MATLAB code which
calls triangulation_node_to_element(), which
reads datafiles describing a set of nodes, their triangulation, and the
value of one or more quantities at each node, and output a file
that averages the quantities for each element. This operation
in effect creates an "order1" finite element model of the data.

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

**LAKE** is a simulated lake with an island region.

- lake_nodes.txt, a node file;
- lake_elements.txt, an element file;
- lake_elements.pngt, an image of the lake elements;
- lake_values.txt, a value file;
- lake_element_values.txt, the node data, averaged over each element.
- lake_element_values.png, a 3D plot of the lake element values, as produced by triangulation_order1_display(). (We had to temporarily rename lake_element_values.txt to lake_values.txt to do this.)
