Re: Interpolation on scattered data

[Nicholas Jankowski]

 It's not possible to send your own triangulation to griddata(...) and
I need to do because griddata(...) function does not work, it actually
crash Octave. Data come from measurement on many different point in
system and hopefully same triangulation work for interpolation for all
values.

(FYI please keep the mailing list in the conversation, and it is the

can you provide a sample of the data that is crashing Octave? I'd be
curious to see what the specific problem is.

Also, I'm no expert on licensing, but my understanding is you can make
and keep private any changes to the code you want unless you
distribute your modified program in some fashion, in which case you
need to make the source code available along with it.

That said, if it improves the function while maintaining compatibility
I'm sure we'd love to consider any improvement to the code.
