grids_display_test
grids_display_test,
a MATLAB code which
calls grids_display(), which
reads two ASCII
files defining grids or sparse grids in 2D or 3D. The first grid is
plotted "lightly", in hollow blue dots, while the second is plotted
with solid red dots. The image is automatically
saved to a PNG file.
