Dear R-Users,
I am trying to plot an ellipsoid like function that represents some
physical threshold in its eigenvalue space. I am facing a few problems
generating a figure I need for my thesis. A small example looks as
follwos where the two contour3d plots do NOT overlay as desired so you

Dear R-Users,
I am currently trying to fit a tensorial function in its principal
coorinate system. The function is given by:
1~(x1^2 + x2^2 + x3^2 - chi0*(x1*x2 + x1*x3 + x2*x3))/eps0^2 + (x1 + x2
+ x3)/xi0
Where eps0 = 0.0066, chi0 = -0.66 and xi0 =
3 matches
