Does ALGLIB RBF support dimension higher than 3 (4D, 5D or higher dimension)?

Does ALGLIB RBF support dimension higher than 3 (4D, 5D or higher dimension)?

http://www.alglib.net/interpolation/fastrbf.php states that it supports 2D and 3D. So does the current code in ALGLIB 3.9.

I would like to confirm the answer, and check if ALGLIB RBF is going to support higher dimension interpolation (4D, 5D or higher) in the future release.

Solution

  • Follow up after much further research

    No, ALGLIB RBF (as of v3.9) doesn't support high dimensional interpolation (4D, 5D or higher).

    I ended up using Scipy RBF which is verified running 4D interpolation. I didn't have the chance to verify 5D or higher dimension.

    This Scipy RBF Tutorial is very useful to setup a quick working prototype.
