I was quite excited when I noticed APEX has an RBF node built-in:
However, without any document or example, I have no idea how to get it work
Another possibility is just use sop::linearsolver, but while I kinda know how to use it, it's a very generic node that requires a huge amount of parameters. And it's an SOP, so I have to pipe in the all the data as attributes first. It's a big bummer that especially we have a rig::RBFInterpolation sitting right next to us.
I have great news: I've managed to make it work. Not so simple, though. At some point this week I'll have an example file and I'll share it here, probably by Thursday.
that's mostly because APEX lacks a lot of convenience functions that would make working with arrays and therefore assembling such setup a lot easier
like getting an array of attribute values from geo multiplying array with another array per component or also scaling array components with single float sum of an array elements ...
I'm not really sure what is the plan for the future, but I'm very distracted by APEX having all the signatures expanded as a separate node types and it's lacking a lot of signatures also, I'd expect more generic functions with support for all datatypes, especially arrays

this is usually simply an UI thing, it would be the UI's job to guess the correct node type based on the connection, this will come in time! Believe it or not, but when houdini 20 was released, there wasn't even a copy/paste feature haha
