Solve missing interpolation method (cubicspline) by khyox · Pull Request #33670 · pandas-dev/pandas (original) (raw)

By commit 8bb2cc1 scipy.interpolate.CubicSpline method is
referenced in the pandas documentation (see pandas/core/generic.py)
but it is not wrapped by any interpolation method. This PR solves
this by adding the corresponding wrapper. SciPy's CubicSpline
is a cubic spline data interpolator that allows explicit control
of the boundary conditions for the interval.
