Well, actually this derives from the input syntax of a numerical code for
structural analysis I had written in Matlab some time ago, where inputs was
matrices... The points I need to plot can be a lot, and are nodes of
structures, while lines are beams, so when I started coding this program in
Maxima I thought that, from an user point of view, who is most likely using
wxMaxima, it was better to enter and see its input in a better ordered
structure (a matrix) raher than in a list. Indeed, a list would be better
to handle in the code.

Thanks for the hint about args(), it will be useful to improve my code.
