**circle_segment_test**,
a FORTRAN90 code which
calls circle_segment(), which
carries out various computations associated with a circle segment,
using gnuplot to illustrate some of the computations.

circle_segment, a FORTRAN90 code which carries out computations associated with a circle segment, including height, angle, area, centroid, sampling, and quadrature, creating some graphics plots using gnuplot.

- circle_segment_test.f90, calls all the tests.
- circle_segment_test.sh, runs all the tests.
- circle_segment_test.txt, the output file.

Test number 6 creates some samples of points in circle segments, and writes out data files and gnuplot command files to create graphics:

- sample01_boundary.txt, data defining the boundary of the circle segment.
- sample01_commands.txt, commands to gnuplot to create a plot.
- sample01_data.txt, the sample data.
- sample01.png, the plot
- sample02_boundary.txt, data defining the boundary of the circle segment.
- sample02_commands.txt, commands to gnuplot to create a plot.
- sample02_data.txt, the sample data.
- sample02.png, the plot
- sample03_boundary.txt, data defining the boundary of the circle segment.
- sample03_commands.txt, commands to gnuplot to create a plot.
- sample03_data.txt, the sample data.
- sample03.png, the plot
- sample04_boundary.txt, data defining the boundary of the circle segment.
- sample04_commands.txt, commands to gnuplot to create a plot.
- sample04_data.txt, the sample data.
- sample04.png, the plot
