- circle_arc_grid.m, computes grid points along a circular arc.
- r82vec_print_part.m, prints "part" of an R82VEC.
- r8mat_write.m, writes an R8MAT file.
- timestamp.m, prints the current YMDHMS date as a time stamp.

- circle_arc_test.m, calls all the tests.
- circle_arc_grid_test01.m, calls circle_arc_grid to make a grid along a 90 degree arc.
- circle_arc_grid_test_output.txt, the output file.

**ARC** is a set of 10 equally spaced points from 0 to 90 degrees,
on a circle of radius 2 centered at (5,5).

**PENTAGON** is a set of 6(!) equally spaced points from 0 to
360 degrees. This is the easiest way to get a pentagon, but
you should really edit the file and remove the last point, since
it repeats the first one. The alternative is to specify that
the angles range from 0 to 288 degrees!

- pentagon.txt, the data
- pentagon.png, an image of the points.
