Dear friends:
Now I have many points which are on a 3D
surface.
for
example,tab={{-5,0,0},{-4,0,1},{-3,0,2},{0,0,5},{3,0,2},
{4,0,1},{5,0,0},
{-4,1,0},{-3,1,1},{0,1,4},{3,1,1},{4,1,0},
{-3,2,0},{-2,2,0.8},{0,2,3},{2,2,0.8},{3,2,0}};
I want to find the z value of (x=3.5,y=1.5) by the
method
of Interpolation,what should I do?
Is there any other method to solve those problem like
this?

Best Regards,
Liwen,
