This manual page documents briefly the gvb command.
gvb is a program that lets the user simulate waves and vibrations with given starting positions,
calculation method and graphical appearance.
It's easy to get the GUI nearly stuck if started with too much points; the maximum of points that an
average computer can manage while remaining responsive is probably about 200. An exception is given by
the fact that if you are dumping frames to create an animation, probably you want a good quality and
won't mind if the GUI is almost stuck.
Also pay attention to the fact that the "eig" mode requires a lot of precalculation; in this mode,
calculating in 2 dimensions with just 15 points per dimension can already require some minutes, depending
on CPU power.
