Hi Adam,
sorry for the late reply. It looks flat because the fluctuations you
were expecting to see are too small compared to the difference between
the maximum and the minimum value, which is huge (about 10^86). You can
use the z option of plot3d; for instance:
plot3d (f(x,y), [x, -4, 4], [y, -4, 4],[z,-100,100],
[mesh_lines_color, true],
[colorbox, true], [grid, 150, 150])$
you will have to experiment with different ranges to find the one that
will show you the region you want to see.
Regards,
Jaime
