Dear Simon,
Thank you for your comment. For the sake of time I just kept the current implementation while saving weights. I guess it could later be used as a reference to benchmark your approach.
Best regards,
Edouard

Hi Edouard,
I'll keep an eye out for your pull request, or perhaps you could send me a note on your use case to my gmail address. My approach just consists of saving the interpolation weights in a sparse matrix then doing a sparse multiply for subsequent interpolations. Weights can be either multi-linear or using barycentric co-ordinates on regular grids; it's an arbitrary choice unless you have a simplicial grid layout you prefer.
Cheers -- Simon

This is clearly a duplicate of your previous post (How can I search the mailing list?).
Yeah, good question .... that's kind of problematic at the moment. Eventually we'll switch to Mailman 3 which has a sane search interface. Sorry, we don't have a better answer than using Google et al. right now.
I think this is a basic task for many geoscientists.
I did not make the effort to understand Simon Clift smarter approach. But I already implemented a quick solution using a switch for the two use cases. May I submit a pull request?
It's now come up a couple of times, so clearly there's interest. Yes, opening a PR would be very helpful.
Cheers, Ralf

Edouard,
I think this thread touched on that a bit: https://mail.python.org/pipermail/scipy-dev/2019-May/023540.html
So Simon Clift might have already some functional code for that which could serve as a starting point.
I personally would be certainly interested in the functionality.

Dear scipy developers,
One could use /scipy.interpolate.RegularGridInterpolator/ at different times with different values but the same source grid and target

Currently this would recompute the indices each time the function is called. I would like to add the possibility to provide the target points at initialisation and the values when calling the object.
