fd1d_display, a MATLAB code which reads a pair of files defining a 1D finite difference method (FDM) model, and plots the data.
ARCTAN contains sample data from the arctangent function at 29 non-uniformly spaced nodes.
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.
