plot_test

plot_test, a FreeFem++ code which investigate features of the plot() command.

The plot() command can display images during the execution of a FreeFem++ script, and can store images in PostScript files. However, the details of what can be plotted, how it can be displayed, and how the plot can be manipulated, are only briefly described. The examples in this directory are intended to ask, and answer, certain questions related to plotting.
