Luc Maisonobe commented on MATH-366:
------------------------------------
I understand the rationale behind adding Bivariate versions of some interfaces
instead of using the general Multivariate form.
I fear adding Trivariate versions is a path to QuadriVariate and so on ... So
I'm a little uncomfortable with these, and would need further rationale to get
convinced. Could you elaborate a little more about the need ?

> Key: MATH-366
> URL: https://issues.apache.org/jira/browse/MATH-366
> Project: Commons Math
> Issue Type: New Feature
> Reporter: Gilles
> Priority: Minor
>
> Similarly to the "BicubicSplineInterpolator", I propose to add a
> "TricubicSplineInterpolator" class.
> This will also require the following:
> # Add methods in "BicubicSplineInterpolatingFunction" (to compute the partial
> derivatives)
> # Add a "TrivariateRealGridInterpolator" interface
> # Add a "TrivariateRealFunction" interface
> # Add a "TricubicSplineInterpolatingFunction" class (to compute the spline
> coefficients from the sampled function, and its partial derivatives)
> Is it OK to perform the changes?
