[SciPy-User] splines with imposed tangent at start and end point

[Del Citto Francesco]

Thanks a lot, we’ll have a look to it!

Obviously, I would have preferred this to be already part of standard SciPy, to avoid compiling additional custom modules and rely on “official” packages, but it is already a good starting point.

Thanks again,
Francesco

[Shameless plug] https://github.com/scipy/scipy/pull/3174

This is not merged yet, and there is some discussion on the interface (comments welcome). I guess it's easy to just grab the spline construction code (make_interp_spline and its cython helpers) and use splev for evaluations.

Hi all,

I’m sure I’m not the first one asking a similar question, but I was not able to find an answer yet.

I need to define a 1D spline curve in the 3D space where both the coordinates and the tangent at first and last points are assigned.
scipy.interpolate.InterpolatedUnivariateSpline can build a spline passing through many points, but no constraint on the tangent can be given.

I’ve found other spline formulations where this is possible, but I was wondering if there is anything already available in SciPy.

Thanks in advance,
Francesco
