Cubic spline.

splinart.spline.spline.spline(xs: ndarray[tuple[Any, ...], dtype[floating]], ys: ndarray[tuple[Any, ...], dtype[floating]]) → ndarray[tuple[Any, ...], dtype[floating]]#

Return the second derivative of a cubic spline.

Parameters:

  • xs (np.ndarray) – The x coordinate of the cubic spline.

  • ys (np.ndarray) – The y coordinate of the cubic spline.

Returns:

The second derivative of the cubic spline.

Return type:

np.ndarray

splinart.spline.splint module#

Integration of a cubic spline.
