Gilles commented on MATH-1166:
------------------------------
bq. BicubiSplineInterpolatingFunction \[...\] would still be deprecated
Correct.
bq. two different implementation, this new one and the piecewise one?
Yes.
The new implementation is also "piecewise". We should decide whether the names
should be changed to something more specific.
Also, there must be a way to build N-dimensional interpolation schemes, but the
current {{Tricubic...}} is tied to a buggy implementation, so it's better to
remove it, and perhaps think how a new one can be modular and use the different
alternative implementations at runtime...
