Here is the power of Haskell - I have implemented some interpolations in
terms of Vector spaces, that is you can interpolate Vectors, Matrices,
Functions, or whatever you like:
However this code is specialised to interpolate between adjacent objects
in a stream, and needs numeric-prelude, and you have to declare an
Algebra.Module.C Double (HMatrix Double)
and this would be an orphan instance that should better go to an
official separate package ...
