2018-04-16 17:49:14 +0200 | commented question | Correct input for list_plot3d(..., interpolation='spline') Here's an example (if I understand correctly) of some points having 'nice' x and y coordinates: pts=[(0,0,1),(1,0,2),(0,1,2),(1,1,5)]. Using pts instead of the six points given in the post yields the same TypeError. Can you get a smooth surface from any point set? A single functioning example would be of great help. But I guess I'm off to read the source code: /scipy/interpolate//_fitpack_impl.pyc |

The following returns the expected piecewise linear surface suggesting that there is a special restriction on the input when using the
Question: What is the correct input to obtain a best fit polynomial surface going through the six points in $\mathbb{R}^3$? Edit: As pointed out by @slelievre, since these six points lie in a common plane, the corresponding surface should be the plane containing the points. So why does |
