**histogram_data_2d_sample_test**,
a C program which
calls histogram_data_2d_sample() to
demonstrate how to construct a Probability Density Function (PDF)
from a table of sample data over a 2D region, and then to use that PDF
to create new samples.

histogram_data_2d_sample, a C program which demonstrates how to construct a Probability Density Function (PDF) from a frequency table over a 2D domain, and then to use that PDF to create new samples.

- histogram_data_2d_sample_test.sh, runs all the tests.
- histogram_data_2d_sample_test.txt, the output file.

**TEST01** computes 1000 samples, based on a 20x20 PDF table
that is heavily biased toward the northwest corner.

- test01.txt, 1000 sample points generated by the program.
- test01.png, a PNG image of the data.

**TEST02** computes 1000 samples, based on a 12x8 PDF table
that is loosely based on the population of counties in Iowa.

- test02.txt, 1000 sample points generated by the program.
