polygon, a FORTRAN90 code which computes properties of an arbitrary polygon in the plane, defined by a sequence of vertices, including interior angles, area, centroid, containment of a point, convexity, diameter, distance to a point, inradius, lattice area, nearest point in set, outradius, uniform sampling.

- polygon_test.f90, a sample calling program.
- polygon_test.sh, runs all the tests.
- polygon_test.txt, the output file.
