• fd1d_display.m, calls all the tests.
• fd1d_display.sh, runs all the tests.
• fd1d_display.txt, the output file.

ARCTAN contains sample data from the arctangent function at 29 non-uniformly spaced nodes.

• arctan_nodes.txt
• arctan_values.txt
• arctan.png, a PNG snapshot of the plot.

PAIR shows how a plot is made when there are two columns of data in the "values" file. The first column is a copy of the original ARCTAN data, and the second column is some perturbed values.
