**tet_mesh_quad_test**,
a FORTRAN90 code which
calls tet_mesh_quad(), which
reads information defining a tetrahedral mesh, and estimates the integral of
a function whose values are given at the nodes.

tet_mesh_quad, a FORTRAN90 code which estimates the integral of a function over a region defined by a tetrahedral mesh.

- tet_mesh_quad_test.sh, runs all the tests.
- tet_mesh_quad_test.txt, the output file.

**CUBE_4x4x4** is a set of nodes in the [0,4]x[0,4]x[0,4] cube, which have
been arranged into an order 4 tet mesh.

- cube_4x4x4_nodes.txt, the node file.
- cube_4x4x4_elements.txt, the element file.
- cube_4x4x4_values.txt, the values file, containing the value of x+2y+3z at each node.
