Hello,

I am working out of NR (2nd ed.) and I plan on using some of the routines for interpolation in 2 and 3 dimensions. All I have are the function values on the grid.

My concern is about interpolatiing in 3 dimensions. Do you have any suggestions on particular routines for this purpose? Which one might be best for this problem.


Thank you,

Ricky

hi,
could anyone help me by telling how to convert the 2D interpolation(bicubic spline) given in NR to 3D.
It would really be helpful if someone can help me to find it out.
thank you.
