[Octave-bug-tracker] [bug #35178] griddata: cubic interpolation not yet implemented

[Nicholas Jankowski]

Follow-up Comment #11, bug #35178 (project octave):

Well, at least 8 [1]. Trusting the 'not-a-knot' statement pins down the
'cubic' in 1D as s^3(x) is equal across splines endpoints. Need to make sure
that's interpreted correct for 2D nodes / edges.    The 'natural' one was
pretty straight forward as having 'endpoint curvatures = 0'.
