Follow-up Comment #5, bug #45295 (project octave):
Hi Sven,
although you get some invalid control points (Inf and Nan) in the structure
for the second derivative, those invalid points should only affect the knot of
the discontinuity. I have tried the examples and the computations in the
interior of the elements using nrbdeval work correctly, both for curves and
surfaces.
Regards,
Rafa
