DIL interpolation over n dimensions [message #87728]

hello,
I'm looking for an N-D interpolation (on lookup tables) in IDL,
something like Vq = interpn(X1,X2,X3,...,V,X1q,X2q,X3q,...) from M****B

Do you have any idea, maybe using some recursive call to interpolate, but I'm pretty lost using this kind of feature in IDL,

Or did someone kept the routine from Peter Albert interpolate_n.pro
The link here belong looks dead

Best regards
Pascal
