I think , Software like Maple,..., is doing it much easier, for example:

plot3d(sin((x^2+y^2))/(x^2+y^2)),x=-10..10,y=-10..10);

But I would like to know something else:
Can anybody tel me , where I can find comparisons between PV-WAVE and
IDL especially the newest versions and may-be between those ane Matlab?
I think all three are very expansive.
