triangulation_quad, a MATLAB program which estimates the integral of a function over a triangulated region.

Source Code:

• triangulation_quad_test.m, calls all the tests.
• triangulation_quad_test.sh, runs all the tests.
• triangulation_quad_test.txt, the output file.

EXAMPLE is a set of nodes in the unit square, which have been arranged into an order 3 triangulation.

• example_nodes.txt, the node file.
• example_elements.txt, the element file.
• example_values.txt, the values file, containing 4 values at each node. (These values are actually the values of 1, x, y, and x*y, which have exact integrals of 1, 1/2, 1/2, and 1/4.) Only the first three integrals will be estimated exactly.
