I'm working with finite element meshes. I make them in Octave. To plot
them, the contour of each "finite element" is a curve with 4 or 5
points depending if the element is a triangle o quadrangle, so that I
have to plot a lot of curves, let's say 5,000 curves (finite
elements). Now, the "matlab-style" plot commands have the problem of
not allowing more than a limited number of curves. So that I use
directly gplot for plotting meshes.
