Follow-up Comment #5, bug #35178 (project octave):
I've implemented the 'v4' method in response to bug #33539. I could look at
'cubic' and 'natural' as well if someone can suggest a particular cubic model.
a quick search shows there are a couple of options depending on what matlab
chose. from the help it only says:
'cubic' Triangulation-based cubic interpolation supporting 2-D interpolation
only. Continuity: C2
'natural' Triangulation-based natural neighbor interpolation supporting 2-D
and 3-D interpolation. This method is an efficient tradeoff between linear and
cubic. Continuity: C1 except at sample points
