Hi Guys,

got my last Problem solved :) Now i do have a new one...

restart; with(RealDomain); with(CodeGeneration); with(ExcelTools); with(plots);
dx1:=133;
dy1:=132;

n := 1; 
for i to 256 do 
for j to 256 do 
r := evalf(sqrt((i-dx1)^2+(j-dy1)^2)); 
Ints := R0[i, j]; 
IntsR[n] := [r, Ints]; 
n := n+1 
end do; 
end do; 
IntsR := [seq(IntsR[i], i = 1 .. n-1)]

The list IntsR consists of unsorted values doublets. Now it would be nice to get some sort of mean value of my Ints over r.  Didnt really find a solution for it until now... do you have any hint?

heya,

i got a problem. I got a list "L" of 3d points [[x1,y1,z1],[x2,y2,z2],..[xi,yi,zi]](in maple), i can easily plot the with pointplot3d(L, axis=normal) but i would need to have them plotted in a contourplot (not the 3D one but the 2d) with contourlines at every full number (1,2,3..highest z value) (well i wont get higher z values then 20)

could you plz tell me how to do that ?

thanks michael
