   .. py:method:: cubic_spline_function(x)

      Evaluate the cubic spline basis function.

      Args:
          x (float or array): Input value(s) to evaluate the spline basis function.

      Returns:
          float or array: Result of the cubic spline basis function.



   .. py:method:: eval(x)

      Compute a 3rd-degree cubic spline with 4-point support.

      Args:
          x (float or array): Input value(s) to compute the spline.

      Returns:
          indices (array): Indices of the spline support points.
          coefficients (array): Normalized spline coefficients.



   .. py:method:: eval_N(x, N)

      Compute a 3rd-degree cubic spline with 4-point support.

      Args:
          x (float or array): Input value(s) to compute the spline.

      Returns:
          indices (array): Indices of the spline support points.
          coefficients (array): Normalized spline coefficients.
