Cubic Spline Periodic BC Not Implemented Error #155
Description
Hello,
Thank you for the library. I am trying to use
interpax.CubicSpline(s_kp, keypoints, axis=0, bc_type="periodic"),
but I am encountering a NotImplementedError.
According to the documentation (https://interpax.readthedocs.io/en/latest/_api/interpax.CubicSpline.html), periodic boundary conditions are supported. However, after inspecting the source code, it appears that periodic boundary conditions are explicitly not implemented (i.e., errorif(bc_type == "periodic", NotImplementedError) followed by bc_type = (bc_type, bc_type)).
I just wanted to bring this discrepancy to your attention in case it is unintentional or the documentation needs to be updated.
Best regards,
Ulas
