I'd like a more direct method that is stand-alone - not dependent on IDL, for instance.Īny thoughts about how this could be done? I'm willing to use open-source libraries, but it would be nice to not have to. This class returns a function whose call method uses interpolation to find the value of new points. There are a number of excellent texts on this subject (such as IDL Programming Techniques by David Fanning, Practical.
IDL INTERPOLATE CODE
The size of my data is larger than my existing code (written in IDL) can handle, and converting to spherical space is unnecessary for my purposes. x and y are arrays of values used to approximate some function f: y f (x). I only want to interpolate within the sphere, however: for points corresponding to r
